Full textThe thesis goal is to demonstrate the feasibility of voltage controlled oscillator (VCO) challenging the VCOs using III-V technologies regarding phase noise performances. This VCO must be fully integrated, target the Ku-band and use the QUBiC4X process from NXP Semiconductors. This thesis work is based on three main chapters, the first one reviews the fundamentals to understand the intrinsic phenomena in electronics components and more particularly in oscillators. The second explains, by using the waveforms analysis and analytical demonstrations, the choices made regarding both the active part and the resonator architecture in order to minimize the AM/PM noise conversion and then to reach the best phase noise performances. It describes the four versions of the realized VCOs and analyzes the post-layout simulations results to justify their fabrications. It shows more specifically an innovative architecture using the advantages of a cascode configuration and a resonator based on three interlocked differential inductors. Finally, the third chapter focuses on the masks' layout and measurements results of the four VCOs. It also details the investigations made to explain the differences between measurements and simulations

Full textBackground and objectives Besides their big benefits, transport activities also cause negative effects for the society including traffic congestion, accidents and environmental pollution. From the perspective of social justice the question arises whether the level of environmental impacts is unequally distributed between different groups of the population. In Germany this question is primarily answered by health science literature. In relatively small samples people were asked about their socio-economic situation and the level of exposure of pollutants was determined at their places of residence. In doing so, it was possible to prove that people of a lower socio-economic status suffer from levels of air pollution and noise above average. However, extensive environmental data and statistics concerning the whole population of a wider study area were hardly involved. Hence, the present dissertation examines how the burden of traffic related noise and air pollution is distributed between socio-economic groups. In addition to the absolute exposure, health impacts are taken into account. Spatial statistical reference units within the selected research area of Berlin are used in order to consider even small and local differences. However, this descriptive analysis does not involve the normative assessment of whether an unequal distribution should be classified as “unfair” from the perspective of society and science. Valuation of environmental effects For the analysis of the socio-spatial distribution of noise and air pollutants, reasonable and easily manageable indicators are necessary in order to aggregate the absolute environmental levels of exposure spatially as well as for socio-economic groups. For this purpose, cost factors are developed according to the concept of external costs. Additionally to the analysis of the socio-spatial distribution, this procedure allows the depiction of the economic consequences of environmental impacts. External costs value the environmental impacts which are not included in the decision making process of users for their trips. Instead, originally uninvolved third parties are affected by those impacts. Regarding road traffic, railway as well as aircraft noise the relevant health effects are high blood pressure and cardiovascular diseases including infarction and nuisances. Concerning air pollution a method is developed which allows the valuation of respiratory and cardiovascular diseases caused by nitrogen oxide and particulate matter based on the concentration of air pollutants in the outside air. The relation between the dose and its response, which describe the risk increase of environmental effects, are taken from the literature and form the basis of the valuation. The treatment costs of diseases, the costs of employment losses as well as the costs of life years lost are additionally included in the cost factors. The cost factors per person and year vary according to the level of exposition. Methodology After the development of exposure based cost factors every registered resident of Berlin is matched as precisely as possible with the noise and air exposure at the place of residence as well as with socio-economic data. All data is taken from official sources, but have not been merged together before. 1. Noise exposure is stated in the strategic noise map, which includes the modelled noise level of all residential buildings in Berlin differentiated by LDEN for road, railway, aircraft as well as total noise. Limiting the sources of noise to the main roads results in inaccuracies in regards to the dominating road traffic noise. A lot of inhabitants which live along secondary roads are therefore only exposed to very low noise levels depending on the underlying model. Hence, the underestimation of the number of exposed people is expected. In order to deal with this methodological issue, the underestimation is quantified by the detailed strategic noise map of Dresden and an exemplary complete mapping of one district which considers the whole road network as a noise source. Based on this, a sensitivity analysis for Berlin is implemented, which assumes a minimum exposure to road traffic noise throughout the whole city. 2. Data on air pollutants exists as modelled exposure to nitrogen oxide and particulate matter. It is available as a raster map of the urban background exposure as well as a network map of the additional traffic-related exposure along the arterial roads. During the data preparation road segments are matched with the specific exposure. 3. Within the official statistics two indicators describing the socio-economic composition of the population are available on the level of road segments. The first one is the proportion of people receiving social welfare benefits (SGB-II) and the second one is the proportion of people with migration background. On average 120 inhabitants live in one of those road segments. The preparation of the data focuses on merging the environmental and social data on the level of road segments. The external costs are calculated using the number of people exposed to traffic related noise and air pollutants as well as the cost factors. Results When initially concentrating on the environmental pollution, an unequal distribution appears. According to the strategic noise map about 30 % of the population is exposed to noise levels LDEN > 55 dB. A small proportion suffers from high exposures. Multiplying the number of those people with the corresponding cost factors, the total noise exposure results in about 130 million Euro per year. Road traffic noise causes the biggest share of cost followed by aircraft noise. Correspondingly the highest noise pollution occurs in the area of the airport Berlin-Tegel (TXL) and in a wide corridor along the Berlin circular railway called “Ringbahn”. All inhabitants of Berlin suffer from air pollution, albeit to different degrees. In regards to particulate matter about 142,000 people and respectively 81,000 people regarding nitrogen oxide are exposed to levels above the legal threshold values. The costs for society arising hereby accumulate to 1.9 billion Euro per year. While finding the highest levels of exposure close to the city center, the pressure falls with distance to the center. Examining the external costs of air pollution, road segments with a higher proportion of people with migration background are by the factor of 2.8 considerably more affected than road segments with a lower rate of migration. A medium correlation occurs between the rate of migration and a high exposure. Concerning road traffic noise the factor between low and high rates of migration background is 3.4 (factor 1.9 for the rate of social welfare benefits respectively). There is a low correlation between the rate of migration and the level of exposure. The strategic noise map for road traffic noise includes only the exposure along the main roads. The quantification of the underestimation shows that the number of people exposed to noise above LDEN > 55 dB is about 52 % higher than reported in the strategic noise map of Berlin. The highest underestimations occur within the range of 55 < LDEN < 65 dB. The different level of exposure between high and low rates of migration background and of social welfare recipients remains when assuming road traffic noise exposure for all buildings in Berlin within the sensitivity analysis. Beyond the status quo analysis, the data allows an evaluation over time. Comparing the strategic noise maps from 2007 and 2012, reductions in the noise exposure can be determined subject to methodological limitations. Measures of the noise action planning for instance were intensively implemented in road segments with higher shares of people with migration background as well as recipients of social welfare. However, an effect of these measures on the distribution of noise exposure according to migration and social welfare rates cannot be proven. The highest potential for noise reductions lies in the relocation of air traffic from TXL to the airport Berlin Brandenburg (BER). While strongly reducing the number of exposed people in Berlin, the number of exposed people in the state of Brandenburg will only rise to a small extent. Overall the number of people suffering from aircraft noise with LDEN > 55 dB will drop from 256,000 to 38,000. Because of the structurally diverging density and composition of the population surrounding the airport BER, almost only areas with currently low migration and social welfare rates will be exposed after the beginning of operation at the airport. Conclusions and further research The presented unequal distribution of noise and air pollution is likely to mark the lower threshold of the real situation. A reason is among other aspects the social distribution within a complex of buildings where for example the structure of rear buildings is ignored. Furthermore, there is evidence that further discrimination such as poor accessibility or bioclimatic impacts additionally reinforces the unequal distribution. By means of the methodological approach and the available data, it is not possible to analyze the initial causes of the current structure. Research concerning external costs reveals that rents are lower for apartments with higher noise exposure. Lower rents in turn are likely to attract people with low incomes. For this reason, even when reducing the environmental pollution, the unequal distribution would persist. Hence, the unequal distribution gives cause to reduce the exposure to noise and air pollutants as follows: 1. The increase of environmental pollution for people who belong to a socially disadvantaged population group should be prevented. The conducted comprehensive analysis can be used as a basis of assessment. 2. The current level of exposure must be reduced in absolute terms. Only in doing so, more people get the chance to live in an environment which benefits their health. 3. When prioritizing measures the socially disadvantaged population groups should be considered among other factors. Improving the methodological approach and the transfer to other study areas requires the availability of data. On the one hand, data about the socio-economic structure for small reference units needs to be existent. On the other hand, the environmental data needs to mirror the real levels of exposure and its structure must be suitable for further processing. The evaluation of socio-economic data gives room for further research with regard to its suitability for analyzing distributions within the social context. Besides trying to find the causes of the unequal distribution, the role of the polluters as well as the possibility to create a balance between the polluters and the exposed individuals should be considered. From a methodological perspective for instance the increasing use of smartphones can contribute to the measurement of environmental exposures and human activities on a larger scale. This could improve the data quality of noise and air pollutants, which currently only partly meets the real levels of exposure. In the long term it could be easier to shape infrastructures and general conditions such as the costs of transport in a way that the environmental impacts of people is reduced

Full textGitterstrukturer har fått mycket uppmärksamhet som cellulära material under de senaste åren på grund av deras enastående egenskaper, t.ex. hög hållfasthet i förhållande till vikt, värmeöverföring, energiabsorption och förmåga att förbättra buller-, vibrations- och bullerskador (NVH-beteende). Denna typ av struktur har fått ett uppsving av tekniken för additiv tillverkning (AM), som kan tillverka geometrier i praktiskt taget vilken form som helst. På grund av ekonomiska och miljömässiga krav används lättviktsdesign i allt större utsträckning inom bilindustrin och byggnadsutrustning. NVH-egenskaperna är en viktig fråga för anläggningsutrustning. De konventionella konstruktionernas NVH-beteende bestäms dock huvudsakligen av massan, vilket innebär att tystnad ofta kräver tunga system, vilket leder till ökad energiförbrukning och större utsläpp. Miljötrenderna och den ekonomiska konkurrens som följer av detta har därför begränsat de traditionella (tunga) lösningarna för att förbättra NVH-egenskaperna och gjort lättviktsdesignen svårare. Nya lösningar är nödvändiga för att lösa svårigheten och utmaningen med att kombinera NVH- och lättviktskrav. I den här forskningen genomfördes topologioptimering på en komponent för en ny ledad transportörtransmission (NAHT) för att balansera lättvikts- och NVH-beteende. Den topologioptimerade 3D-modellen fylldes med en icke-homogen gitterstruktur med optimal gittertäthet via storleksoptimering. Gitterstrukturoptimering är en typ av topologioptimering, och det är termen för att beskriva dessa förfaranden. För att tillverka den komplicerade gitterstrukturen krävs additiv tillverkning (eller 3D-utskrift) (efter topologi- och gitterstrukturoptimering). De nya modellerna analyserades med hjälp av finita elementmetoden (FEM), och resultaten av analysen jämfördes med resultaten av de ursprungliga modellerna. Efter jämförelsen erhölls positiva resultat, vilket visar att optimering av topologi och gitterstruktur kan tillämpas vid utformning av komponenter för byggutrustning. Enligt resultaten kan optimering av gitterstrukturen skapa en tillförlitlig lättviktsdesign med bra NVH-beteende. Dessutom har gitterstrukturens organisering och layout en betydande inverkan på den totala prestandan.

The influence of impulsive nonlinear noise caused by occasional “clipping” of the subcarrier multiplexing signal on laser diode in the hybrid AM/QAM SCM fiber CATV system is discussed in the thesis. The clipping noise can be described as a Poisson impulse train and its main influence in the hybrid system is the BER degradation of the M-ary QAM television signal. One of the subjects in the thesis is the computer simulation of the hybrid AM/QAM SCM fiber CATV system with one or more M-ary QAM digital television channels using the cable digital television standard DVB-C proposed by DVB project in Europe. With the simulating results, we can predict and observe the BER performance affected by the clipping noise of the M-ary QAM channel in the hybrid AM/QAM system. At last, we propose a simple method to determine the maximum number of M-ary QAM channels which can add to an existing AM SCM fiber CATV system for upgrading to a hybrid AM/QAM SCM fiber CATV system.

In this thesis, three types of CMOS MMICs in 0.18-?m CMOS technology were designed for LTE and WiMAX applications, which include low-voltage high-balance voltage controlled oscillators (VCO), self-biased mixer, and phase-locked loop with AM-to-PM noise suppression. In the first type of CMOS VCOs, there are three taped-out chips designed at 3.5 GHz, which are a 1-V quadrature voltage-control oscillator (QVCO), and 0.7-V/0.45-V differential VCOs. The QVCO was designed with an dynamic transconductance matching technique for eliminating the output amplitude imbalance. The measurement result shows that the phase error is < 0.8°and the amplitude error is < 6.9 %. The phase noise is from -130.6 to -133.7 dBc/Hz at 1-MHz offset frequency from the carrier over the 3193 to 3605 MHz tuning band. The power consumption is 4.4 mW from a 1 V supply. The 0.7 V and 0.45 V differential VCOs were designed for low-voltage operation by using the body bias to reduce threshold voltage, the dynamic transconductance matching for amplitude balance, and a drain noise filter for the thermal noise suppression of the current-source. The measurement result shows that the operating voltage can be as low as 0.7 V and 0.45 V. The power consumption is 0.76 mW from a 0.45 V supply, where the phase noise is less than -122 dBc/Hz at 1-MHz offset from the carrier of 3367-3919 MHz and the phase error is 2.3°and the amplitude error is 2.9 %. The power consumption is 3 mW from a 0.7 V supply, where the phase noise is less than -121 dBc/Hz at 1-MHz offset from the carrier of 3387-3696 MHz and the phase error is 0.3° and the amplitude error is 2.8 %. The self-biased active mixer utilizes the LO-induced dc voltage to dynamically bias the MOSFET such that conversion gain can be obtained without needing external dc power supply. The measurement shows that the designed mixer MMIC has a measured voltage gain of 4.6 dB with zero dc power consumption. The input is -12.5 dBm and the noise figure is 20.7-24.5 dB for the RF band of 2.0 to 4.0 GHz and 10 MHz IF frequency. The implemented frequency synthesizer includes a non-linear phase frequency detector (PFD), charge pump (CP), sigma-delta modulator, and the voltage-control oscillator with AM-to-PM noise suppression. The measured phase noise is -99.0 dBc/Hz at 1 MHz offset and the settling time is 30 ms. the power consumption is 20.1 mW from a 1.7 V supply.
