Full textEsta tesis estudia los cambios en la oferta de crédito de los bancos cuando se enfrentan a incertidumbre, supervisión regulatoria y políticas macroprudenciales. El primer capítulo propone un nuevo índice para detectar la incertidumbre idiosincrática de los bancos a nivel trimestral. Para desarrollar la nueva medida, utilizo técnicas de aprendizaje de máquinas y procesamiento del lenguaje natural sobre los discursos trimestrales hechos por la gerencia de cada banco. Encuentro que una mayor incertidumbre está asociada con un menor préstamo el próximo trimestre y una mayor liquidez, lo que sugiere un manejo activo de la incertidumbre. El segundo capítulo explora cómo los bancos responden a la supervisión maquillando sus balances. En preparación para la revisión de calidad de activos (AQR) de 2014 en Europa, los bancos revisados redujeron su participación en bonos y préstamos riesgosos. Después del AQR, los bancos volvieron a adquirir bonos más riesgosos en sus balances, pero no créditos más arriesgados. En el tercer capítulo, estudio cómo la introducción de controles de capital en Colombia afectó el crédito doméstico. Los resultados apuntan a complementariedades entre la oferta de crédito domestico y externo.

Full textThe developed document examines the impact of the Stabilization Fund for the prices of petroleum-derived fuels (FEPC, in Spanish) in macroeconomic variables of interest, such as GDP, inflation and public debt. The main reason for this study is due for the instability generated by volatilities in international oil prices in resource dependent economies, such as Peru. In addition, to identify if the stabilization tools, such as the fund, are executed efficiently without generating adverse effects that could harm other aspects of the economy. The document found empirical evidence on the purpose of price stabilization in various aspects, as well as the birth of their need depending on the country's situation with respect to extractive resources. A model of autocorrect vectors (VAR) was used to estimate the effect of various types of fuels, using international prices and those established by the FEPC. Monthly data were used to make the estimate, for the period 2008-2018 and were extracted from the Central Reserve Bank of Peru and the Supervisory Agency for Investment in Energy and Mining. The synthesis of the investigation indicated that the FEPC fulfills its main function of executing a stabilization of fuel prices, softening external shocks to the Peruvian economy, however, modifications to the fund are required due to collateral effects that they make it unsustainable over time.

Full textLa tesis doctoral parte del descubrimiento del neologismo “Bad Fans” encontrado en una crítica publicada en The New Yorker escrita por Emily Nussbaum, crítica de televisión. En este texto se cuestionan las emociones de algunos espectadores en la recepción de la serie de televisión Breaking Bad (AMC, 2008 - 2013, Vince Gilligan). A raíz del descubrimiento de este neologismo, se plantearon las preguntas de dónde, como y por qué surge este neologismo y qué significa. Para ello se hace un largo estudio sobre la narrativa desarrollada por la serie Breaking Bad dentro del conjunto de la televisión contemporánea norteamericana y su inclusión en la denominada “Complex TV” (televisión compleja). El trabajo desvela determinadas características, entre ellas, el desarrollo de la narración de una forma determinada, que, entre otras cosas, busca la confusión de las emociones de los espectadores a través de los distintos recursos narrativos. Se hace necesario el estudio sobre el perfil del espectador contemporáneo y de las emociones que surgen, sobre la base de que se crean a partir de factores cognitvos y fectivos / comunicativos. Así mismo, se estudia la creación del significado que construye la narración y la que hace el espectador sobre la misma. Este espectador contemporáneo vive hiperconectado, participa e interactúa, comparte y recibe extensiones de la propia narración, entre las que se incluyen los textos de los críticos de televisión. En consecuencia se analiza el papel de la crítica de la televisión y de algunos de los textos aparecidos sobre Breaking Bad, para evaluar la narración y constatar la existencia y la importancia del pluralismo crítico, que acepta el diálogo con el espectador. Se concluye, entre otras cosas, que no hay buenos o malos espectadores, sino también una pluralidad.
The doctoral thesis is based on the discovery of the neologism "Bad Fans" found in a review published in The New Yorker written by Emily Nussbaum, a television critic. In this text, the emotions of some viewers at the reception of the television series Breaking Bad (AMC, 2008 - 2013, Vince Gilligan) are questioned. As a result of the discovery of this neologism, the questions were raised of where, how and why this neologism arises and what it means. To do this, a long study is made of the narrative developed by the Breaking Bad series within contemporary North American television and its inclusion in the so-called “Complex TV” (complex television). The work reveals certain characteristics, among them, the development of the narrative in a certain way, which, among other things, seeks to confuse the viewers' emotions through the different narrative resources. It is necessary to study the profile of the contemporary viewer and the emotions that arise, on the basis that they are created from cognitive and affective / communicative factors. Likewise, the creation of the meaning that the narrative builds and that made by the viewer about it is studied. This contemporary viewer lives hyperconnected, participates and interacts, shares and receives extensions of the narrative itself, including the texts of television critics. Consequently, the role of television criticism and some of the texts that have appeared on Breaking Bad are analyzed to evaluate the narrative and verify the existence and importance of critical pluralism, which accepts dialogue with the viewer. It is concluded, among other things, that there are no good or bad spectators, but also a plurality.

Full textThe purpose of this research is to evaluate the financial and tax impact of disbursements for own content and transmission rights based on IAS 38 "Intangible Assets". Television channels are the main source of information, according to CONCORTV in 2017, citizens indicate that one of the media that has a greater presence at the local and regional level is television, although there is a certain dissatisfaction on the part of the citizen with respect to programming, since it is not cultural or educational. We are interested in investigating the own contents and transmission rights from the perspective of the intangible at the accounting level to be a particular case in a sector little investigated. The methodology used is the non-experimental design, the scope is exploratory research, since it is an accounting research plan applied in Peru, and the size of the sample is the television channels that have a greater market share, which concentrates 84 % in the telecommunications sector. This thesis will be developed in five chapters. In the first chapter, local and international investigations will be described. In the second chapter, the problems are posed, the hypotheses to be validated and the proposed objectives. In the third chapter, we will proceed to describe the methodology to be used is a mixed approach. In the fourth chapter, the results of the qualitative and quantitative analysis are presented and it is embodied in a practical case with which it is intended to identify capitalization disbursements by own content and transmission rights, identify the independent variables which can generate expectation of materials represent in the financial statements. In the fifth chapter conclusions and recommendations are analyzed.

Full textEl trabajo estudia el comportamiento de la tasa de ahorro de los hogares en el período 1985 a 2016. Se examinan las variables que la literatura considera determinan la tasa de ahorro de los hogares a largo plazo: renta, riqueza, desempleo, crédito obtenido, endeudamiento, ahorro público, estructura de la población, prestaciones sociales, tipos de interés y nivel de precios. En el marco metodológico del modelo de corrección de error contrastamos la cointegración de las variables mediante cuatro especificaciones de la tasa de ahorro en función de los siguientes determinantes a largo plazo: la renta laboral como proxy de la renta permanente, la riqueza, el desempleo, el crédito, la tasa de dependencia y las prestaciones sociales. Se excluyen otras variables potencialmente determinantes de la tasa de ahorro de los hogares: interés y precios debido a su escasa significatividad; o, como en el caso del ahorro público, por no presentar muestras de cointegración. Los resultados nos permiten obtener la contribución de las variables a las variaciones de la tasa de ahorro de los hogares en el período de estudio: muestran la especial relevancia a largo plazo de la tasa de dependencia confirmando la relación entre estructura demográfica y tasa de ahorro. Relacionado con la estructura demográfica y la legislación social, las prestaciones sociales inciden en gran medida sobre la tasa de ahorro y muestran su relevancia para la supervivencia del estado de bienestar. De carácter más coyuntural, el crédito y el desempleo determinan la tasa de ahorro a largo plazo en cualquier fase del ciclo económico. La variación de la renta laboral, como proxy de la renta permanente, incide sobre la tasa de ahorro especialmente en los cambios de ciclo cuando se modifican las expectativas sobre la renta permanente. Encontramos que la riqueza incide de forma continua aunque menos relevante. Finalmente, encontramos evidencias no consolidadas de que los desequilibrios sobre la tasa de largo plazo se corrigen a corto plazo mediante variaciones de la renta laboral, la riqueza y el crédito. El modelo obtenido muestra la incidencia sobre la tasa de ahorro de la crisis financiera y consecuente contracción del crédito, tanto en 1991 como especialmente en 2008. Construimos un modelo reducido de la tasa de ahorro de los hogares derivado del anterior que muestre la relevancia de los aspectos financieros sobre la tasa de ahorro de los hogares: pretendemos demostrar que una actuación pública de política financiera más decidida y anticipada ante la crisis bancaria de 2008 habría mejorado el crédito a los hogares y la gestión del ciclo económico. Para ello estudiamos la situación del sistema bancario español mediante un conjunto de variables como el coeficiente de solvencia y la tasa de morosidad y su relación con el crédito concedido a los hogares desde 2008. Comparamos la actuación de política financiera en España y en dos países europeos que implementaron ayudas al sistema bancario: planteamos un escenario alternativo en el que esa intervención de política financiera en España hubiera tenido lugar de forma más decidida y a tiempo, como se hizo en los países europeos objeto de comparación. Aplicamos en ese escenario alternativo una versión reducida del modelo de la tasa de ahorro propuesto y estimamos la repercusión sobre la tasa de ahorro de los hogares. Bajo nuestras hipótesis la contracción del crédito y restricción de liquidez habría sido menor: los resultados obtenidos muestran una evolución menos reactiva de tasa de ahorro de los hogares y menor repercusión potencial de la crisis iniciada en 2008

Full textLa presente tesis tiene como objetivo principal conocer, analizar y describir, de forma detallada, el perfil socioemocional de los músicos adolescentes y los directores musicales, integrantes de las bandas juveniles de la Comunidad Valenciana y los coros juveniles de Cataluña. Para ello hemos confeccionado un exhaustivo marco teórico, estructurado en torno a tres grandes ejes: la educación emocional a través de competencias; la adolescencia y la música; y las agrupaciones musicales juveniles. Este marco teórico ha servido como base fundamental para el diseño y la realización de nuestro estudio empírico, enmarcado dentro de una metodología no experimental o ex post facto de tipo descriptivo y comparativo-causal. El estudio consiste en aplicar diferentes instrumentos psicométricos a una amplia muestra de adolescentes integrantes de una agrupación musical juvenil (n = 660), concretamente de 10 bandas de la Comunidad Valenciana y 10 corales de Cataluña, y a sus respectivos directores musicales. Con su aplicación, además de describir las variables de los adolescentes músicos relacionadas con elementos socioemocionales, también pretendemos establecer relaciones de causalidad entre éstas y las obtenidas por un grupo de adolescentes no músicos (n = 655). Los resultados confirman que la participación en este tipo de agrupaciones tiene un notable impacto tanto personal como social. Los adolescentes músicos poseen un desarrollo socioemocional significativamente superior a los adolescentes no músicos. También se han establecido similitudes y diferencias entre los componentes de las bandas y las corales, asimismo, se ha realizado un análisis pormenorizado sobre el perfil socioemocional de los directores que lideran dichas agrupaciones.
The main goal of the present PhD dissertation is to identify, analyze and describe in detail the teenage musicians and the musical conductors’ socioemotional profile, who are members of a youth band from the Valencian Community or belong to a youth choir from Catalonia. To this end, we have developed an exhaustive theoretical framework structured around three main axes: emotional education through competences; adolescence and music; and youth musical groups. The theoretical framework has functioned as a fundamental basis for the design and implementation of our empirical study. It has been, framed within a non-experimental or ex post facto methodology, using both descriptive and comparative-causal analysis techniques. The study consists of applying different psychometric instruments to a large sample of adolescents, who are members of a youth musical group (n = 660), in particular 10 bands from the Valencian Community and 10 Catalan choirs, and their respective musical conductors. With the use of those instruments, we try not only to describe the variables of the adolescents musicians, related to socioemotional elements, but also to establish relations of causality between these and those obtained by a group of non-musicians (n = 655). The results confirm that the participation in this type of groups has a remarkable personal and social impact. Teenage musicians have a significantly higher socioemotional development than non-musicians. Similarities and differences have also been established between the components of the bands and the corals. Finally, a detailed analysis of the socioemotional profile of the conductors, who lead the groups has also been conducted.

Full textDuring the 1990s, Peru was in an unstable political situation due to previous internal conflicts and changes that occurred in the world. Population, then, adopts a pragmatic attitude in search of national reconstruction; attitude that can be seen reflected in the artistic production of the time. In this context, this research work seeks to analyze how hedonism is represented in the music videos of the Peruvian band “Nosequien y los Nosecuantos” during the 90s. For its development, at first; the video clip role in the communication process will be explained. Subsequently, hedonism will be defined as a moral doctrine. And finally, the sociocultural context of the 90s in Peru will be described. This research article will be based on an interpretive worldview and will be done with a qualitative approach. Likewise, the methodological technique that will be used to obtain data will be that of content analysis.

Full textThe objective of this study is to analyze the impact of diversification on performance and risk. A monthly frequency data panel is used for the period 2010-2019 and the MGM estimator is used because of the dynamic nature of the model. The results show that loan portfolio diversification does not affect the performance of the banking system, however, it is observed that banks with higher risks can increase their returns by increasing their level of concentration by economic sector and department. The effect on risk will depend on the type of concentration, a higher level of loan concentration by sector and department will decrease credit risk; but a higher concentration of loans by type of credit will increase the level of risk. Besides, it was noted that there is no effect on risk or return depending on whether the bank is domestic or foreign-owned. The findings are important for banks when choosing their credit strategy and key for regulatory authorities.

Full text"Implementation and Evaluation of Tobacco control Policies in Hospitals" Background: Several studies have shown that tobacco control policies favour the cessation of tobacco use, increase population support and improve compliance with smoke free policies. However, the impact of tobacco control measures in Catalan hospitals is unknown. Hypothesis: 1) The smoke free policy in hospitals reduces the prevalence of tobacco consumption among workers and increases compliance with smoke free regulations; 2) Law 28/2005 has increased tobacco control policies in hospitals; 3) has decreased second-hand smoke (SHS) levels among Catalan hospitals; 4) European hospitals which have developed the European smoke free model (ENSH) have low levels of SHS in different areas; 5) the smoking cessation program addressed to hospital employees achieves a high rate of abstinence. Aims: 1) To describe the effects on tobacco consumption after the gradual implementation of tobacco control policies in a hospital; 2) to evaluate the progression of tobacco control policies in hospitals members of the XCHsF before and after the implementation of Law 28/2005, 3) To assess the impact of tobacco control Law 28/2005 on exposure to SHS in public hospitals in Catalonia, before (2005) and after (2006) its implementation. 4) To describe the levels of SHS by the assessment of PM2.5 particles in a sample of European hospitals in 2007; 5) to evaluate the effectiveness of a smoking cessation program addressed to hospital workers. Methodology: Five studies have been conducted, which were: a series of cross-sectional surveys, a pre-post evaluation of tobacco control measures, two studies for the assessment of SHS- one in Catalonia, and another in 7 European countries- and a study evaluating the effectiveness of a smoking cessation program. Results: The tobacco consumption at one hospital dropped from 34.5% in 2001 to 30.6% in 2006. Smokers changed their consumption patterns with the reduction of the number of cigarettes smoked per day and the decrease of daily smokers. The average score of the implementation of tobacco control policies in hospitals was 52.4 (95% CI 45.4 to 59.5) in 2005 and 71.6 (95% CI 67.0 to 76.2) in 2007 (up 36.7%). The average median concentration of nicotine decreased 56.5% after the implementation of Law 28/2005. However, nicotine was found in hospitals halls, emergency rooms, fire escapes and cafeterias. The median concentrations of PM2.5 in a sample of 30 European hospitals were low (3.0 ug/m3). The abstinence probability of the XCHsF tobacco cessation program at 6 months was 0.504 (95% CI 0.431 to 0.570). Workers with higher nicotine dependence showed a lower likelihood of abstinence (0.376, 95% CI: .256 to .495) than the low-dependence (0.529, 95% CI 0.458 to 0.599). There is a high probability of abstinence among workers treated with combined drug therapy (bupropion and nicotine replacement) (0.761, 95% CI 0.588 to 0.933). Conclusions: Tobacco control policies in hospitals are associated with a slight decline in smoking consumption, reduction of levels of SHS, and high probability of abstinence at 6 months.

Full textPsoriasis is a chronic cutaneous disease that has been linked with metabolic syndrome. The present study aimed to evaluate the presence of alterations in anthropometric and serum parameters related to metabolic syndrome in psoriatic patients, along with their changes after treatment with narrow-band UVB. Fifty psoriatic patients were compared with 50 gender, age and body mass index-matched controls in a cross-sectional study. Additionally we evaluated the study parameters in the patients before and after a course of narrow-band UVB phototherapy. Patients were prospectively recruited in the Department of Dermatology of Hospital Parc Taulí excluding the months of high solar irradiance. Controls were matched with patients according to their characteristics. Patients with psoriatic arthritis and patients and controls with a list of inflammatory diseases were excluded. The evaluation consisted of a panel of anthropometric and laboratory determinations, that were obtained at the moment of inclusion, and in the patients after completion of phototherapy. These determinations included a glycaemic, inflammatory and lipid profile, vitamins and adipocytokines. The study population showed overweight. With a comparable body mass index, psoriatic patients had a higher fat content as determined by electric bioimpedance, which was correlated with waist circumference. They also had higher serum concentrations of LDL-cholesterol, apo-B, leptin, lipocalin-2, retinoid binding protein-4 (RBP-4), and soluble receptor of TNF. Vitamin D levels were low (<20 ng/ml) in patients and controls, and it markedly increased after phototherapy in patients, without correlation with PASI (Psoriasis Area and Severity Index) improvement. Initial PASI correlated with basal high sensitivity C-reactive protein, lipocalin-2 and RBP-4. At the completion of phototherapy, the patients showed a decrease in their IL-6 and ferritin levels, in correlation with total cumulative UVB dose. In healthy controls, principal components analysis yielded a protective component against metabolic syndrome, which was not present in the patients. Patients showed a different positioning of omentin, lipocalin-2, resistin and RBP-4 in principal components’ map when compared to healthy controls. In conclusion, we identified in psoriatic patients without arthrtitis a different metabolic and anthropometric profile when compared to healthy gender, age and body mass index-matched controls. Vitamin D insufficiency was common in both study groups, and increase in its synthesis after phototherapy did not correlate with psoriasis improvement. Our results add new data that clarify the role of certain adipocytokines in the genesis of inflammatory and metabolic disturbances in psoriatic disease.

Full textThe purpose of this work is to determine the relationship between sales promotion actions, delving into the mileage points accumulation program and its relationship with customer loyalty of banking entities in Metropolitan Lima. Due to its characteristics, the research is correlational, with a non-experimental design and a mixed approach. For its corroboration, two types of research were established: qualitative and quantitative. That is why a qualitative study was essentially based on the realization of two focus groups, ranging from 25 to 35 years. In addition, interviews were conducted with 2 experts from the banking and finance sector who are proficient in the use of mileage accrual. On the other hand, the quantitative was conducted via an online survey with a sample of 247 people. Finally, the results obtained determined that there is a relationship between the accumulation of miles points and the loyalty of customers through the use of a credit card, showing a moderate positive degree of correlation, that is, it exists, but not fully consolidated. For this, the Pearson statistic was used in the IBM SPSS program. In addition, implications and recommendations for management are included, mentioning future research.

Full textThis thesis focus on the development of innovative filtering technologies that enhance the performance to meet the filtering requirements for spacial communications. It is part of the ANR project ATOMIQ coordinated by Thales Alenia Space with partners (SPCTS 3D CERAM). The first chapter consists of a literature review on the Q and V band filters as well as 3D manufacturing technologies. The second chapter is devoted to the development of a new formulation of highly pure, low losses and temperature stable alumina. The third chapter presents a microwave filter design in Q and V band based on a dielectric resonant cavity. The fourth chapter is about the manufacturing of filters and presentation of various demonstrators manufactured by stereolithography and low pressure molding. It also provides a post-production correction solutions based on laser shoots. This work is original because, to the best of our knowledge, 3D ceramic stereolithography and the low pressure molding have not been used to produce small sizes Q and V band microwave filters

Esta investigación tuvo como soporte teórico los diferentes enfoques de la Educación Sexual integral, como así también el concepto de prácticas educativas desde la propuesta de la Educación integral y otros autores como Fierro (1999) y Gimeno (1997). Mediante un exhaustivo análisis de la información recabada, se pudo responder a los principales intereses de esta investigación como caracterizar a docentes de ambas instituciones educativas del nivel medio, en términos de variables sociodemográficas, explorar los enfoques que manifiestan los docentes acerca de la sexualidad y reproducción adolescente, en relación a enfoques tradicionalistas, biomédicos, sexológicos, jurídicos, y de género y, por último, describir las prácticas educativas y/o institucionales que conllevan a cabo los docentes para abordar la educación sexual y reproducción adolescente, teniendo en cuenta los contenidos, secuencia y abordaje pedagógico y recursos didácticos entre otros. En lo que respecta al marco metodológico, se trata de un tipo de estudio exploratorio descriptivo que fue analizado desde un enfoque mixto. Se dividió en dos etapas de análisis, una etapa cuantitativa en dónde se analizaron las respuestas a las preguntas cerradas de las entrevistas realizadas a docentes. En la etapa cualitativa se analizaron las respuestas a las preguntas abiertas de las entrevistas realizadas a docentes. La muestra fue de carácter no probabilística e intencional ya que los docentes fueron elegidos teniendo en cuenta ciertos criterios de selección muestral. Las fuentes de datos fueron de orden primario, debido a que la información surgió de las entrevistas semi estructurada y en profundidad. En el análisis pertinente se pudo determinar que los docentes se encuentran interesados y motivados en enseñar Educación Sexual en sus clases, y se encuentran predispuestos a capacitarse en Educación Sexual Integral (ESI), con el propósito de vencer ciertos prejuicios aún existentes al momento de abordar determinados temas. En el presente trabajo se han podido conocer las prácticas pedagógicas llevadas a cabo por los docentes para abordar contenidos de Educación Sexual y reproductiva, llegando a la conclusión que aspectos fundamentales como la correcta selección de materiales didácticos para impartir las clases, son importantes para fomentar la motivación y participación de alumnos y alumnas.

Full textPronation and flat feet have, for a long time, been associated, particularly in their relationship to injury. However, this relationship has been questioned in view of the divergent results in writings. Recently, the dissociation between foot-type and foot-function has highlighted a possible link between pronation and low back pain. The study of pronator subjects' way of moving, identified by foot function tests, could highlight the biomechanical risk factors associated with low back pain. The general objective was to identify and study the kinematic and plantar pressure impact of pronation while walking. Then to evaluate the effect of preventive treatments aimed aimed to limit the biomechanics at risk while keeping primary prevention in mind. Three studies were conducted. A concordance study between different pronation identification tests, under different conditions, was carried out in order to select an appropriate test for the study of gait. Gait kinematic and baropodometric analyses of 159 pronator vs non-pronator professional firefighters were then compared. Then, the effects of two one-month protocols aimed at reducing pronation (foot muscle strengthening or wearing insoles) were suggested to pronator subjects. Agreement between the different tests of foot-function identification was found to be low. A combination of functional tests was used to refine the identification of pronation. Pronator subjects showed plantar pressure and kinematic differences in the forefoot, hindfoot, knee and pelvis. These kinematic effects may reflect a risk factor for low back pain. Pronation was reduced by both preventive protocols wich were accompanied by kinematic changes in the foot and hip. Although our preventive protocols do not show an impact on the pelvis, they do show a kinematic change in the lower limb that could modify the biomechanics of the pelvis and provide a mean of preventing low back pain

Full textLegal relations are based essentially on the monetary obligations. The dominant role of money is explained by its legal and economic functions. The daily flow of money transfers attest this importance. If those legal and economic relations are usually located in a limited geographical area, they now follow a movement towards internationalization. The circulation of money also follows the same movement beyond the simple framework of a country. To ensure the funds transfer across borders, various techniques have long time allowed to make international money transfers. Early techniques appeared in fairs of the middle Ages, with the use of commercial paper (bill of exchange or promissory note) and later the check. These traditional instruments which have the characteristic of being based on the paper declined to give way to new techniques. The celerity required by business, has created a need of innovation. It explains the creation of new techniques of money transfer and a new form of currency: the "electronic money”. Another important innovation is the emergence through the computing, "systems" that are a new framework of funds transfers.The foreign element related to international nature of the new techniques of money transfer raises the legal problem of conflict of laws. If for traditional techniques of fund transfer, standardization initiatives (Geneva Conventions on bills of exchange and checks) seem to have solved this problem, there is not presently, any uniform law governing the international use of new techniques of funds transfer. So, is it necessary to consider the nature of contractual relationships which are formed thanks to computing in systems in order to determine a “contract law” able to govern the new techniques of international funds transfers

This study proposed a low insersion loss and small area bandpass filter realized on Forgotten Realms 4 (FR4) substrate for 2.4 GHz applicaitons. For shrinking circuit area, the filter is designed with LC resonator structure, but without the defected ground structure (DGS) which is the most popular method to reduce area. Thus, the filter is shrunk without destory the ground. The measured insertion loss of the filter is 0.9 dB at 2.4 GHz, and the passband ripple is below 1 dB. The -3 dB bandwidth is as wide as 1.8 GHz (from 0.9 to 2.7 GHz). The filter in stop band attenuates larger than 20 dB. The attenuation from 5.4 GHz to 7 GHz is up to 30 dB. The chip area is 19.6 mm × 10 mm. The filter is low cost, small area, and good performance. The filter could be used directly in 2.4 GHz communication system.

Communications require the separation of the transmitted and received signals, which can be made by using ferrite materials for its non-reciprocity. When an external DC magnetic field is applied, the magnetic dipoles will align with the DC magnetic field. Right-hand and left-hand circularly polarized waves will experience different effective permeability and then have different propagating constant, resulting in the non-reciprocity. A stripline circulator is developed by using the ferrite material of yttrium iron garnet. The geometry of the central stripline is optimized for its insertion loss and bandwidth. In this article, a circulator was developed for 4G LTE communication band 3 of 1710 - 1880 MHz. With a maximum insertion loss of -0.35 dB, minimum reflection and isolation of -20 dB, the bandwidth of the developed circulator is 384 MHz, much better than the required value of the 4G band 3. We also have done the theoretical analysis at the same time and give explanation to broad bandwidth. Base on the previous experience, we set a design procedure of stripline circulator for different frequency ranges and successfully design a stripline circulator for another frequency range by following the procedure. Finally, we’ve proposed a way to decrease the applied DC magnetic field in the circulator and keep the working bandwidth simultaneously through researching the effect of magnetic properties of the YIG.

The purpose of this dissertation is to develop broadband and low-loss band selection filters in microwave and millimeter-wave frequencies and their applications in standard CMOS-based technology, which include the a CG dual-band LNA for UWB and Ku band wireless receiver, and a X-band low phase noise oscillator for second and third harmonic frequency suppression. In the first part of this dissertation, the proposed dual band stopband filter and Q-band standing wave VCO with a novel dual mode loop resonator are presented. The proposed dual mode loop resonator not only significantly shorten the length of a resonator but also provide a frequency selection coupled structure (FSCS) to implement the dual band microstrip bandstop filter. The dual center frequencies of the BSF are designed at 2.1 (fs) and 6.4 GHz (3fs) with 20 dB fractional rejection bandwidth as over 100% and 10 %, respectively. In addition, the proposed dual mode loop resonator has low loss and much stronger selectivity than that of spiraling and meandering layouts, hence it is suitable to implement a tunable millimeter-wave VCO with a tunable P-N junction capacitiance technique. Theoretical prediction, simulation, and measurement demonstrate that the VCO achieves a tuning range from 38.77 to 43.62 GHz (BW = 12.5 %). The peak output power is 1.5 dBm with power efficiency of 3.8 % at 40.56 GHz. The minimum phase noise is -121dBc/Hz at 1 MHz offset. In the second part of this dissertation, the band selection filters with a novel frequency-selecting coupling structure (FSCS) are proposed. Since, the proposed FSCS is realized by a slow wave anti-coupled line which is realized by a shorted circuit at a shunted transistor. The proposed lowpass filter and bandpass filter can be reconfigured by switching the on/off state of a transistor which presents either open or short termination of condition. Meanwhile, two reconfigurable transmission zeros can be produced for wide passband operation and wide stopband with good rejection level. Beside, the external cross coupled capacitance can improve the upper side passband selectivity and stopband bandwidth. The proposed filter features of compact size and good passband/stopband performance which is attractive to implement a CG dual-band LNA, and an X-band low phase noise oscillator applications.

Various V-band CMOS 360° active phase shifters were designed in this thesis for the applications in beam-steering phased array systems. Typical full 360° phase shifters have a large loss variation when the phase is tuned. This induces a significant amplitude-modulated noise. To overcome this difficulty, a new integrated-surfrange configuration was proposed, where the entire 360° is divided into one, two, or four smaller tunning surfrange. Because smaller tunning range can reduce the low variation and circuit complexity, the overall mention low variation the require varactor ratio can be dramatically reduced. The new 360° integrated-subrange configuration controls of a reflection-type phase shifter with 360° in phase range, switchable differential low-noise amplifier,and quadrature phase inverters. Three phase shifter were designed in this thesis. First, V-band differential reflection-type phase shifter (DRTPS) was design in 180 nm CMOS process. The strong coupling transformer was utilized to realize the quadrature hybrid such that the loss variation is lowered and the chip size is reduced. This DRTPS can be improved to the asymmetric type of reflection-type phase shifter (ADRTPS), where the input and output characteristic impedances of the transformer are different, for the further loss variation reduction. These DRTPS and ADRTPS were used as the fundamental building blocks of the following full 360° active phase shifters. Second, the Two-subrange 360° phase shifter is composed of a switchable differential low-noise amplifier, where the switchable differential low-noise amplifier is used to has 180 phase inversion and signal amplification. Therefore, the full 360°range can be achieved by a switch control. This 90nm CMOS 360° V-band active phase shifter has a measured gain of 11.5±0.7 dB, noise figure of 6.3 dB at 60 GHz. The second 90nm CMOS 360° phase shifter, based on the ADRTPS has a simulated gain of 12.0±0.4dB, noise figure of 6.2 dB at 60 GHz. Third, the quadra-subrange 360° phase shifter is composed of 90° DRTPS, the switchable differential low-noise amplifier and 0°/90°phase shifters. The simulated gain is 12.2±0.5 dB and the noise figure is 6.0 dB at 60 GHz. The design methodology, circuit simulation and measurement results will be described in detail.

In this thesis, a second-order T-type bandpass filter with sharp lower band-edge selectivity is presented. For an LTCC filter, the conductor loss is often more dominant than the dielectric loss in the RF range. Therefore, the design of high-Q inductors is very important as it has significant influence on the passband insertion loss. Here, in order to achieve high-Q, we proposed a new T-type structure, and used vertical via pairs to replace planar inductors. The simplified procedure of T-type bandpass filter is analyzed in detail. Note that, all the published literatures used side electrode. Nowadays, the space of cell phone is limited, and each component is requested much smaller. In addition to miniaturized size, using bottom electrode can also reduce the area of welding. This thesis is the first work using only bottom electrode which decreases PCB using space and is more difficult in design. A bandpass filter of 2.4-2.5 GHz was designed and measured based on Low Temperature Co-fired Ceramic (LTCC) technology. The filter shows good attenuation at the 1.8-1.9 GHz GSM and WCDMA bands, especially at 2.11-2.17 GHz IMT-band which is important for mobile bands of cellular phones. This filter uses only bottom electrode and the filter’s overall size is 1.6mmx0.8mmx0.508mm. In the next part, a third-order cross-coupled filter structure applied for the same 2.4-2.5GHz is designed. The attenuation at 2.11-2.17GHz of the filter is better than 25dB. Compared to T-type filter, this filter has better attenuation at the 1.8-1.9 GHz, but has bigger inband insertion loss. This filter also uses only bottom electrode and the filter’s overall size is 1.6mmx0.8mmx0.528mm. Compared with the full-wave electromagenetic designed responses, the measured results slightly shifts toward the lower frequency. Nevertheless, the correlation of the simulated and the measured results agrees very well.

This thesis studies two important circuits in RF front-end, including power amplifiers (PAs) and low-noise amplifiers (LNAs). This thesis introduces power performance of PAs. We use Load Pull system to measure some high voltage power devices using TSMC 0.18μm SiGe BiCMOS technology. By Observing the change of currents near P1dB for different bias points and for different output impedances (RHi、RLO) based on Load Pull contours, we can judge what gain compression mechanism happens for any specific bias point. When choosing different load impedance, the device will experience other gain compression mechanism. Therefore, knowing these operation characteristics help us design PA easily and know power devices’ limitations. On the other hand, we use the method of power constrained simultaneously noise and input match to optimize the dual band (2.4/5.2GHz) low noise amplifier. Besides, the analysis of optimization and design flow of a dual band LNA are illustrated in this thesis. However, the noise figure minimum (NFmin) changes when using none-ideal components, especially the input LC-tank. It causes a noise spike (resonant frequency) between two operating bands. As a result, how to improve noise figure is one of the important things in this thesis. We use three different technologies and methods to reduce the impact of non-ideal inductors to suppress loss brought by inductors and make noise figure lower. This thesis demonstrates three 2.4/5.2 GHz concurrent dual-band LNAs using MEMS integrating 0.18-μm CMOS, 0.18-μm SiGe BiCMOS wi/wo bondwire inductor and 0.11-μm CMOS (high resistive substrate), respectively. All of these doings are to reduce the impact by non-ideal inductors, especially LC-tank. Finally, the thesis demonstrates two single band 2.4-GHz LNAs using 0.11 μm CMOS to show its design trade-off. This claimed noise optimization design method is demonstrated and finally discussed through the measurement results.

This thesis presents the design of millimeter-wave (MMW) CMOS low-insertion loss phase shifters and W- / K-band CMOS T/R switches. The K-band phase shifter (PS) is fabricated using standard TSMC 0.18-μm CMOS technology. To achieve full 360° phase control, a (fixed) switch-type 180° phase shifter is applied to the continuous 180° reflection-type phase shifter for the phased-array antenna system. The K- and W-band T/R switches are fabricated using standard TSMC 0.18-μm and 90-nm GUTM CMOS technologies, respectively. The first W-band (75 - 110 GHz) switch is designed by using series-shunt structure with body-floating technique to improve the insertion loss and linearity performance. To enhance the isolation performance, the parallel inductor and leaking cancellation technique are adopted. The second W-band series-shunt type switch uses the double parallel-path structure. In addition, the body-floating, parallel inductor and stacked transistor techniques are used to improve the overall performance. In the K-band switch design, the chip size is much reduced by using the stacked inductor. All the measurements are performed by using the on-wafer measurement setup.

In this thesis, I designed 2pcs low cost microstrip line passive filters for WiMAX IEEE802.16 system application and designed a low conversion sub-harmonic mixer by using AlGaN/GaN high electron mobility transistor, HEMT. The first part is Band-pass filter (BPF) which can be used for IEEE802.16 (WIMAX) wireless communication protocol .Those are 5.8GHz 1/2λ open stubs circuit Band-pass filter and the others is 2.5GHz~ 3.7GHz 1/4λ Parallel-Coupled circuit Band-pass filter which are based on the Chebyshev low-pass filter prototype. Second part of the thesis is a low conversion loss sub-harmonic Mixer which be implemented by AlGaN/GaN high electron mobility transistor, HEMT process for Anti- parallel Schottky barrier diode (APDP) technology. This mixer also employed CMRC (Compact Microstrip Resonator Cell) loss pass filter for better exhibit band stop and can be optimized through individually turning the reflection phase for different frequencies.
