Full textAs the technological processes of integration on silicon evolve by increasing the fine engraving and the integration density, digital processing has become faster at a lower cost in area and power consumption. This reduction in size is made at the expense of analog blocks' precision. The idea is to take advantage of the performance offered by digital circuits to release the specifications for analog blocks and globally win area occupation and consumption. Yet, analog-digital mixed circuit designers are faced with a situation where they have to choose between a purely analog design flow or a pure digital design flow, each ignoring the other. In this thesis, we introduced a new mixed-signal design flow, which aims at unifying both digital and analog design flows. Our design flow is divided into three steps: a placement step, a global routing step and a detailed routing step. During the placement step, the designer describes the relative placement and a set of constraints and our placement tool will generate all the valid placements respecting these constraints. The global routing step determines approximately the shortest path to connect the connectors according to a netlist. The shortest paths take into account several constraints such as symmetry constraints or avoiding obstacles. Finally, the detailed routing step completes the construction of each wire and resolve overlap issues of the wires. Our design flow has been applied to several analog and mixed-signal circuits, placed and routed within a few seconds. Our main goal is to give control to the designer all along the layout design flow steps

Full textThis thesis deals with Soft failure localization in the analog and mixed mode Integrated Circuits (ICs) by means of Dynamic Laser Stimulation techniques (DLS). The results obtained using these techniques are very complex to analyze in the case of analog and mixed ICs. In this work we develop a methodology which facilitates the analysis of the laser mapping. This methodology consists on combining the experimental results (laser mapping) with the electrical simulations of laser stimulation impact on the device. The influence of photoelectric and thermal phenomena on the IC (transistor level) has been modeled and simulated. The methodology has been validated primarily on test structures before being used on complex Freescale ICs existing in commerce

Full textMixed-signal applications are among the fastest growing market segments in the electronics and semiconductor industry. This is driven by the growth opportunities in mobile communication, networking, power management, automotive, medical, imaging, and security applications, which all require analog and mixed-signal (AMS) content. One bottleneck exists if the designs include analog components together with digital ones. Digital design has a well-defined, top-down design methodology, but AMS design has traditionally been an ad hoc custom design process, it is more time-consuming interactive process and fully based on designerÕs expertise. The major difficulty is how to model the impact of circuit non-idealities and technology process variations on system- level performances.In this thesis, we present an unified modeling, design and verification platform with a fast sizing and biasing methodology. The proposed methodology propagates the circuit-level non- idealities into system-level simulations in a very natural way. The methodology synchronizes SystemC-AMS TDF MoC and electrical circuit simulator (SPICE), which enables to mix non- conservative system-level model with conservative nonlinear circuit netlist. Besides, we explain how UVM-SystemC-AMS developed in the FP7 Verdi project, provides an unified methodology for the verification of systems having interconnected AMS, HW/SW. In order to explore the effectiveness of the proposed methodology, two case studies are investigated: a 3-stage 6-bit ADC pipeline and a voltage regulator for an implantable telemetric system. The problem of hierarchical design is illustrated in the 3-stage 6-bit ADC pipeline while the problem of system architecture with feedback loop is illustrated in the implantable telemetric system

Full textIn the competition of the miniaturization of integrated electronic circuits, UTBB-FDSOI technologies are better adapted to nanometric sizes, because they can limit the problems due to the random doping variations used in conventional “bulk” transistors and bring a significant improvement in terms of performance and low power design. This thesis is a contribution to the development of novel building blocks for PLL using complementary logic in 28nm UTBB-FDSOI technology. Using this technology, we proposed a complementary inverter based on a pair of back-gate cross-coupled inverters offering a fully symmetrical operation of complementary signals. This design concept can be extended to any digital cells to generate more stable, symmetrical and resilient output signals. First, we designed a fast and efficient ring oscillator composed by four complementary inverters delivering quadrature clocks which oscillation frequency is 7.3GHz. Then using complementary logic and back-gate control structure, we proposed an efficient solution to produce novel structures of VRCO, PFD, Charge pump, divisor etc., which are the key building blocks of high-speed low noise PLLs. All these designs have been simulated and verified using Cadence. Moreover, a test chip of RO, current mirror and VCRO have already been realized in silicon and tested

Full textL'objectif des travaux présentés dans cette thèse est donc la conception et le développement de structures d'auto-test intégré (BIST) permettant le test par histogramme des CAN. L'implantation directe sur silicium de cette technique de test ne serait pas possible car elle nécessiterait un surcoût de silicium important. Pour rendre cette intégration viable nous avons donc été amenés à envisager des solutions originales basées sur la décomposition et l'analyse par histogramme. Cette approche, associée à la mise en place d'un certain nombre de simplifications des calculs d'extraction nous a permis de réduire considérablement les ressources matérielles (mémoires, module de calcul) à intégrer. Enfin, pour compléter cette structure BIST, nous avons conçu une architecture originale de générateur de rampe et de générateur de signaux triangulaires. Ces générateurs utilisent un système d'auto-calibration qui leur permet de générer un signal précis et insensible aux variations des paramètres technologiques tout en impliquant une surface de silicium minimale.

Full textThe growing complexity of modern chips poses challenging test problems due to the requirement for specialized test equipment and the involved lengthy test times. This is particularly true for heterogeneous chips that comprise digital, analogue, and RF blocks onto the same substrate. Many research efforts are currently under way in the mixed-signal test domain. Theses efforts concern optimization of tests at the production stage (e. G. Off-line) or during the lifetime of the chip (on-line test). A promising research direction is the integration of additional circuitry on-chip, aiming to facilitate the test application (Design For Test) and/or to perform Built-In-Self-Test. The efficiency of such test techniques, both in terms of test accuracy and test cost, must be assessed during the design stage. However, there is an alarming lack of CAT tools, which are necessary, in order to facilitate the study of these techniques and, thereby, expedite their transfer into a production setting. In this thesis, we develop a CAT platform that can be used for the validation of analogue test techniques. The platform includes tools for fault modeling, injection and simulation, as well as tools for analogue test vector generation and optimization. A new statistical method is proposed and integrated into the platform, in order to assess the quality of test techniques during the design stage. This method aims to set the limits of the considered test criteria. Then, the different test metrics (as Fault coverage, Defect level or Yield loss) are evaluated under the presence of parametric and catastrophic faults. Some specific tests can be added to improve the structural fault coverage. The CAT platform is integrated in the Cadence design framework environment

Full textWith the development of the Internet of things, the number of connected devices is in constant increase. These objects use a large amount of data including personal credentials. Therefore, security has become a major constraint for System on Chips (SoCs) designers. Moreover, in a context more and more aggressive in terms of performances and time to market, it is important to find low cost security solutions. Although the hardware security is often treated from a digital point of view, almost every SoCs is also using analog and mixed IP. Thus, this work presents different steps to improve the security of analog IPs, from vulnerability analysis to countermeasures design validation, and behavioral modeling in the context of mixed signals and low cost applications. To protect any system, the first requirement is to know its vulnerabilities. To do so, a vulnerability analysis methodology dedicated to analog circuit has been developed. Using the results of this analysis, countermeasures can be designed during the development of the circuit and not at the end. The circuit security is thus improved without dramatically increasing its cost in terms of design time. The analysis of a clock system generator, an analog IP widely used in current SoCs and composed with various sub-circuits, has shown fault attacks using Laser Photoelectric Stimulation (LPS) or supply voltage glitches as important threats. After having identified the 2 previous attacks types as major threats, their effects on analog circuits are analyzed. Existing countermeasures are then compared and evaluated for the protection of analog IPs. To complete these solutions, two analog detectors have been designed to detect laser and supply voltage glitch attacks considering SoCs level constraints. Electrical test of these detectors processed on CMOS 28nm FD-SOI technology proved their efficiency. Theoretical vulnerability analysis has shown some difficulties. Indeed, analog circuits are sensitive to numerous parametrical faults. Also, the high interconnection of various sub-circuits makes the faults propagation analysis quite difficult. To help this analysis, electrical simulations at transistor level are necessary. These simulations are quite long and, so the behavioral modeling of analog circuits to help the analysis of supply voltage glitch attack effects has been studied. To do so, the developed models must be developed according different constraints presented in this report and applied to the behavioral modeling of a real analog circuit. This illustration proved that behavioral models can be used to help to identify which attack shapes are the most likely to induce faults in the circuit

Full textBeing able to check whether an IC is functional or not after the manufacturing process is very difficult. Particularly for analog and Radio Frequency (RF) circuits, test equipment and procedures required have a major impact on the circuits cost. An interesting approach to reduce the impact of the test cost is to measure parameters requiring low cost test resources and correlate these measurements, called indirect measurements, with the targeted specifications. This is known as indirect test technique because there is no direct measurement for these specifications, which requires so expensive test equipment and an important testing time, but these specifications are estimated w.r.t "low-cost measurements". While this approach seems attractive, it is only viable if we are able to establish a sufficient accuracy for the performance estimation and if this estimation remains stable and independent from the circuits sets under test.The main goal of this thesis is to implement a robust and effective indirect test strategy for a given application and to improve test decisions based on data analysis.To be able to build this strategy, we have brought various contributions. Initially, we have defined new metric developed in this thesis to assess the reliability of the estimated performances. Secondly, we have analyzed and defined a strategy for the construction of an optimal model. This latter includes a data preprocessing followed by a comparative analysis of different methods of indirect measurement selection. Then, we have proposed a strategy for a confidant exploration of the indirect measurement space in order to build several best models that can be used later to solve trust and optimization issues. Comparative studies were performed on 2 experimental data sets by using both of the conventional and the developed metrics to evaluate the robustness of each solution in an objective way.Finally, we have developed a comprehensive strategy based on an efficient implementation of the redundancy techniques w.r.t to the build models. This strategy has greatly improved the robustness and the effectiveness of the decision plan based on the obtained measurements. This strategy is adaptable to any context in terms of compromise between the test cost, the confidence level and the expected precision

Full textSemiconductor device fabrication is a complex process which is subject to various sources of variability. These variations can impact the functionality and performance of analog integrated circuits, which leads to yield loss, potential chip modifications, delayed time to market and reduced profit. Statistical circuit simulation methods enable to estimate the parametric yield of the circuit early in the design stage so that corrections can be done before manufacturing. However, traditional methods such as Monte Carlo method and corner simulation have limitations. Therefore an accurate analog yield estimate based on a small number of circuit simulations is needed. In this thesis, existing statistical methods from electronics and non-Electronics publications are first described. However, these methods suffer from sever drawbacks such as the need of initial time-Consuming circuit simulations, or a poor scaling with the number of random variables. Second, three novel statistical methods are proposed to accurately estimate the parametric yield of analog/RF integrated circuits based on a moderate number of circuit simulations: An automatically sorted quasi-Monte Carlo method, a kernel-Based control variates method and an importance sampling method. The three methods rely on a mathematical model of the circuit performance metric which is constructed based on a truncated first-Order Taylor expansion. This modeling technique is selected as it requires a minimal number of SPICE-Like circuit simulations. Both theoretical and simulation results show that the proposed methods lead to significant speedup or improvement in accuracy compared to other existing methods

Full textTo reduce cost and optimize the use of resources, hospitals are prompted to regroup facilities and human resources, especially in the surgical suite. The principle of sharing resources from several surgical specialties in a multi-disciplinary surgical suite raises a number of issues, particularly regarding the design of the new structure (resources sizing, organizational alternatives) and its steering process (scheduling surgery, allocating human and material resources). At the moment, decision makers are lacking tools to address these challenges. This thesis proposes a global decision support methodology for designing the surgical suite and steering the pooled human resources. This methodology involves three main steps. We first carry out the process modeling of existing surgical suites, in order to elaborate a diagnosis and to initiate a methodology for performance improvement. In a second step these existing process models are used as a basis to elaborate models of the targeted process. These new models allow building up an activity simulation tool that enables to generate curves representing workforce requirements. We address the staffing problem of pooled personnel through the design of a set of shifts covering the estimated workload, using Integer Linear Programming (ILP) combined with discrete event simulation. In a third time, we focus on the anesthesiology personnel (nurses and physician), which are generally organized in pools of personnel, and propose solutions to the related scheduling problems. Approaches based on Mixed Linear Programming (MLP) and Constraint Programming (CP) have been developed, experimented and validated in real-world applications

Full textContrary to digital design, analog design suffers from a real delay in the software solution that enables fast and reliable design. In this PhD, three approaches are proposed. The first is the methodological approach. At this level we recommend a "top-down" hierarchical approach. It consists of partitioning the system to size into sub-blocks of elementary functions whose specifications are directly inherited from the system level specification. Next, we aimed to reduce design time through the exploration of optimal solutions using hybrid algorithms. We attempted to take advantage of the rapid global search and local search accuracy. The interest of hybrid search algorithms is that they allow to conduct effective exploration of the design space of the circuit without the need for prior knowledge of an initial design. This can be very useful for a beginner designer. Finally, we worked on the acceleration of time simulations proposing the use of meta-models which present a more reduced time than electrical simulation models. Meta-models are obtained automatically from extracting results of electrical simulations

Full textThe main topic of this work is the design of original radiofrequency active filter topologies in Silicon BiCMOS technology. In a first part, the state of the art of the different existing integrated technologies is described. In a second part, we present the design of the two active filters based on recursive principles. The first circuit, non-tunable, uses a differential amplifier in order to achieve signal summation. The second circuit, based on a cellular approach of recursive filters, can be tuned independently in terms of gain, bandwidth and central frequency. In a third part, we propose two original solutions for the realisation of integrated reconfigurable channelized filters. With such topologies, and using low-order filters, excellent performances can be achieved in terms of selectivity thanks to the generation of transmission zeros

Full textReliability of analog and mixed signal circuits fabricated using complementary metaloxide semiconductor technologies in the deep-submicrometer technology nodes is significantly affected by process, voltage and temperature (PVT) variations. Degradationinduced due to aging mechanisms like bias temperature instability, hot carrier injection leads to additional challenges in design of reliable circuits. PVT variations and aging mechanisms together lead to lifetime degradation of device and circuit performance.There are many studies in the literature of the reliability of MOS transistors. Few studies have been conducted on the impact of their reliability on circuits.This research will study the impact of the deterioration of the MOS transistors on the performance of the developed circuits for analog and mixed applications (low dropout voltage regulator LDO, phase locked loop PLL, voltage controlled oscillator VCO, digital to analog converter CAN, power amplifier PA).Degradation lifetime induces the degradation of the threshold voltage and the drain. The surveys are conducted using aging simulations supporting models of aging mechanisms developed by our team and measurements of circuits implemented in 28nmFDSOI technology. Accelerated tests were used to evaluate the aging effect. Appropriate correction techniques for overcoming aging-induced degradation of circuit performance are proposed and studied.The DC and AC performances of LDO were analyzed before and after aging. The stress induces a degradation of these performances because of the effect of the mechanism of injection of hot carriers (HCI) on the transistors and the Matching induced in the pair of transistors responsible for the regulation. The LDO was oversized to avoid severe damage. A survey of the evolution of yield before and after aging was done using Mundea WICKED tool.The jitter noise and lock time of the PLL are not affected by aging and the PLL itself corrects any degradations and deviations of its output parameters. For this, an investigation of one of its important blocks, the VCO, was made. Measurement results at 125 ° C show that the oscillation frequency of the VCO has undergone significant degradation. While the relative phase noise has not been impacted.The aging effect on the digital analog converter SAR-ADC consisting of 16 TI-ADCs has occurred. Extraction of static and dynamic performances showed a significant degradation of the SNR. In order to identify the block responsible for this degradation, simulations of a single ADC were made. Aging has negligible impact on the switches while the comparator was identified as the most sensitive block. Aging impacts the time windows for each sub-block of the comparator which gives rise to a false decision of one of these blocks, hence a false signal at the output of the comparator, resulting in a code error and a degradation in the performance of the ADC.Investigation of the aging effect on the power amplifier has shown a significant degradation of the PA figures of merit under the effect of RF stress. These impairments are due to the degradation of transistor parameters such as transconductance gm and resistor rds. A solution for improving these degradations has been proposed. Based on the principle of detection and adaptive polarization, this technique makes it possible to change the polarization of the PA in order to bring the degraded performances to their fresh value.Based on this research, it is possible to conclude that the aging mechanisms of the 28nmFDSOI CMOS technology are not a major obstacle to the development of analogue and mixed signal systems. However, a careful analysis of the effects of aging at the circuit level, from the design phase, using the models developed at the transistor level and included in the simulators, is necessary.The incorporation of effective detection and performance enhancement solutions is possible for the implementation of extremely precise circuits

Full textElectronics and semiconductor are evolving at an ever-increasing rate. New technologies are also introduced to extend CMOS into nano/molecular scale MOSFET structures. Tighter time-to-market needs are pressing the need for an automated reliable analog design flow. Automatic layout generation is a key ingredient of such flow whose design challenges are drastically exacerbated when more complex circuits and newer technologies must be hosted. The thesis presents a designer-assisted, reusable and optimized analog layout generation flow that addresses the challenges facing the automation of analog circuits. It is part of CHAMS project developed in LIP6. It has been developed in 3 phases. Firstly, we designed a library of analog Smart Devices that are parameterized, reusable, and with different layout styles. A generic language was used to describe these Devices to ease the technology migration and the layout-induced parameters calculation. Secondly, we developed the tools to generate the layout of complex circuits using the library of Smart Devices, the technology files and the designer's geometrical placement constraints needed to guarantee a certain performance. An intelligent topological representation was used to efficiently place the circuit modules given the designer's set of constraints. Thirdly, we created algorithms to optimize the layouts for different aspect ratios to minimize the area and the routing parasitic. In parallel the algorithm directly calculates and back-annotates the layout-dependent parasitic parameters. This work provides a reliable and efficient solution to allow a fast, optimized and parasitic effects-aware layout generation of complex analog circuits

Full textAs device dimensions of ultra large scale integration (ULSI) integrated circuits continues to scale down, the surface area of MIM (Metal-Insulator-Metal) capacitor has to decrease, thus requiring an increase of capacitance density. However, decreasing the dielectric thickness of conventional insulators such as Si02 (є = 3. 9) and Si3N4 (є = 7) leads to unacceptable electrical performances of the capacitor. Higher dielectric constant materials are developed to cope with continuous performance improvements in advanced capacitors structures. Tantalum oxide has been regarded as one of the most promising dielectric materials due to its high dielectric constant (є = 25) low linearity coefficients and leakage current obtained when it is integrated in MIM capacitors. Physico-chemical properties of TiNfTa2O5/TiN stacks were studied as weil as the electrical performances of the capacitor (conduction mechanisms, model of C(V) curves). , MOCVD, PEALD and ALD deposition methods have been investigated for processing Ta2O5 films. Thanks to various and welladapted characterisation methods (XRR, FTIR-ATR, ERDA, AR-XPS. . . ), we obtain a better understanding of the chemical composition and density of Ta2O5 films, of the interface TiNfTa2O5 properties and of the contamination of MIM structures. We analyzed impact of the deposition method and the influence of various post-treatrnents in order to correlate material properties of TiNfTa2O5fTiN stacks to electrical performances of MIM capacitor

In this line, we present in this thesis different sinewave generation strategies based on harmonic cancellation techniques to design a high-frequency on-chip sinusoidal synthetize. The proposed generators employ digital hardware to provide a set of phase-shifted digital square-wave signals. These square-wave signals are scaled and combined using different harmonic cancellation strategies in a simplified current-steering DAC. The selected generator allows the cancellation of all harmonic components up to the eleventh. Additionally, a simple calibration strategy has been devised to compensate the impact of process variations and mismatch on the effectiveness of the harmonic cancellation. The simplicity of the circuitry makes this approach suitable for mixed-signal BIST applications. Electrical simulations of a 28nm FDSOI design and experimental results are provided to validate the functionality of the proposed signal generator. Obtained results show a calibrated performance around 52dB of SFDR for a generated sinusoidal signal at 166 MHz

Full textThe natural radiative space environment is composed by numerously particles in a very large energy spectrum. From an electronics component point of view, it is possible to distinguish cumulative effects and so-called Analog Single Event Transient effects (ASET). Cumulative effects correspond to continuous deterioration of the electrical parameters of the component, due to a low dose rate energy deposition (Total Ionizing Dose: TID) throughout the space mission. ASETs are caused by a single energetic particle crossing a sensitive area of the component inducing a transient voltage pulse that occurs at the output of the application. During ground testing, both effects are studied separately but happen simultaneously in flight. As a result a synergy effect, induced by the combination of the low dose rate energy deposition and the sudden occurrence of an ASET in the device previously irradiated, occurs. A study of dose-ASET synergistic effects is proposed using an accelerated irradiation test technique known as Dose Rate Switching method (DRS) tacking into account the concern of the Enhanced Low Dose Rate Sensitivity (ELDRS). A High Level Model is developed using circuit analysis to predict the synergy effect observed on a three stages operational amplifier. To predict synergy effect, the TID effect is taken into account by varying the model parameters following a variation law deduced from the degradation of the supply current which recorded during usual industrial TID testing. Finally, the Transient Radiation Effects on Electronics (TREE) phenomena induced by a Very High Dose Rate X-ray pulse environment and the dose-TREE synergy effect are then investigated using an X-ray flash facility. The classical ASETs methodology analysis can explain the shapes of transients observed

Full textSmart Power circuits, used in the automotive industry, are characterized by the integration on one chip of the power parts with low voltage analog and digital parts. Their main weak point comes from the switching of power structures on inductive loads. These inject parasitic currents in the substrate, capable of activating the bipolar parasitic structures inherent in the layout of the circuit, leading to failure or destruction of the integrated circuit.These parasitic structures are not currently integrated into CAD tools nor simulated by SPICE simulators. The extraction of these structures from the layout and their integration into the CAD tools is the objective of the European AUTOMICS project, in which this thesis is carried out.The characterization of the substrate coupling of 2 case study was used to validate theoretical models and compare them to simulations using the new substrate coupling model

Full textThe aim of this thesis is to study the contributions and the limitations of Independently Driven Double Gate MOS transistors in regard of the low frequency analog design. This device is one of the candidates for the replacement of the current bulk MOS technology since the gate length of the transistors cannot be efficiently decreased under 30nm. Even if the IDGMOS technology is mainly designed for digital and radio frequency applications, the independent drive of the gates should also improve the design of analog circuits ant it would provide solutions to the future circuits issues. First, this work focuses upon the IDGMOS’s behaviour, going a little deeper into the effects of the coupling that exists between its interfaces. Using the electrical characteristics of the transistor and simplifying its model, this report then reviews the static and dynamic laws of the component in order to extract a simple description of its operation modes. Secondly, a state of the art concerning both the future environment and issues is presented, followed by the solutions which currently exist using the standard MOS technology. A brief comparison between an advanced MOS technology and an IDGMOS model fitted on the ITRS parameters is given. However, these ideal parameters prevent this work from establishing a practical conclusion whereas the aforementioned theoretical studies can be used for providing a better understanding of the IDGMOS contributions. Those are reviewed just before the last part of the report which presents some basic analog circuits and their enhancement using double gate transistors. This chapter first emphasizes each important aspect of the device operating within the circuits and it thus concludes on an interesting comparison between two complete low supply voltage amplifiers, the first one designed using IDGMOS transistors and the other one based on bulk driven MOS devices
