Sigma Delta converters are a very popular choice for the A/D converter in multi-standard, mobile and cellular receivers. Key A/D converter specifications are high dynamic range, robustness, scalability, low-power and low EMI. Robust Sigma Delta Converters presents a requirement derivation of a Sigma Delta modulator applied in a receiver for cellular and connectivity, and shows trade-offs between RF and ADC. The book proposes to categorize these requirements in 5 quality indicators which can be used to qualify a system, namely accuracy, robustness, flexibility, efficiency and emission. In the book these quality indicators are used to categorize Sigma Delta converter theory. A few highlights on each of these quality indicators are; Quality indicators: provide a means to quantify system quality. Accuracy: introduction of new Sigma Delta Modulator architectures. Robustness: a significant extension on clock jitter theory based on phase and error amplitude error models. Extension of the theory describing aliasing in Sigma Delta converters for different types of DACs in the feedback loop. Flexibility: introduction of a Sigma Delta converter bandwidth scaling theory leading to very flexible Sigma Delta converters. Efficiency: introduction of new Figure-of-Merits which better reflect performance-power trade-offs. Emission: analysis of Sigma Delta modulators on emission is not part of the book The quality indicators also reveal that, to exploit nowadays advanced IC technologies, things should be done as much as possible digital up to a limit where system optimization allows reducing system margins. At the end of the book Sigma Delta converter implementations are shown which are digitized on application-, architecture-, circuit- and layout-level. Robust Sigma Delta Converters is written under the assumption that the reader has some background in receivers and in A/D conversion.

Sigma-delta A/D converters are a key building block in wireless and multimedia applications. This comprehensive book deals with all relevant aspects arising during the analysis, design and simulation of the now widespread continuous-time implementations of sigma-delta modulators. The results of several years of research by the authors in the field of CT sigma-delta modulators are covered, including the analysis and modeling of different CT modulator architectures, CT/DT loop filter synthesis, a detailed error analysis of all components, and possible compensation/correction schemes for the non-ideal behavior in CT sigma-delta modulators. Guidance for obtaining low-power consumption and several practical implementations are also presented. It is shown that all the proposed new theories, architectures and possible correction techniques have been confirmed by measurements on discrete or integrated circuits. Quantitative results are also provided, thus enabling prediction of the resulting accuracy.

A comprehensive overview of Sigma-Delta Analog-to-DigitalConverters (ADCs) and a practical guide to their design innano-scale CMOS for optimal performance. This book presents a systematic and comprehensive compilation ofsigma-delta converter operating principles, the new advances inarchitectures and circuits, design methodologies and practicalconsiderations − going from system-level specifications tosilicon integration, packaging and measurements, with emphasis onnanometer CMOS implementation. The book emphasizes practical designissues – from high-level behavioural modelling inMATLAB/SIMULINK, to circuit-level implementation in Cadence DesignFrameWork II. As well as being a comprehensive reference to thetheory, the book is also unique in that it gives special importanceon practical issues, giving a detailed description of the differentsteps that constitute the whole design flow of sigma-delta ADCs. The book begins with an introductory survey of sigma-deltamodulators, their fundamentals architectures and synthesis methodscovered in Chapter 1. In Chapter 2, the effect of main circuiterror mechanisms is analysed, providing the necessary understandingof the main practical issues affecting the performance ofsigma-delta modulators. The knowledge derived from the first twochapters is presented in the book as an essential part of thesystematic top-down/bottom-up synthesis methodology of sigma-deltamodulators described in Chapter 3, where a time-domain behaviouralsimulator named SIMSIDES is described and applied to the high-leveldesign and verification of sigma-delta ADCs. Chapter 4 movesfarther down from system-level to the circuit and physical level,providing a number of design recommendations and practical recipesto complete the design flow of sigma-delta modulators. To concludethe book, Chapter 5 gives an overview of the state-of-the-artsigma-delta ADCs, which are exhaustively analysed in order toextract practical design guidelines and to identify the incomingtrends, design challenges as well as practical solutions proposedby cutting-edge designs. Offers a complete survey of sigma-delta modulator architecturesfrom fundamentals to state-of-the art topologies, considering bothswitched-capacitor and continuous-time circuit implementations Gives a systematic analysis and practical design guide ofsigma-delta modulators, from a top-down/bottom-up perspective,including mathematical models and analytical procedures,behavioural modeling in MATLAB/SIMULINK, macromodeling, andcircuit-level implementation in Cadence Design FrameWork II, chipprototyping, and experimental characterization. Systematic compilation of cutting-edge sigma-deltamodulators Complete description of SIMSIDES, a time-domain behaviouralsimulator implemented in MATLAB/SIMULINK Plenty of examples, case studies, and simulation test benches,covering the different stages of the design flow of sigma-deltamodulators A number of electronic resources, including SIMSIDES, thestatistical data used in the state-of-the-art survey, as well asmany design examples and test benches are hosted on a companionwebsite Essential reading for Researchers and electronics engineeringpractitioners interested in the design of high-performance dataconverters integrated in nanometer CMOS technologies; mixed-signaldesigners.

This research consisted of creating a specialized simulator for sigma delta data converter designs that was capable of simulating the operation of several different pre-determined circuit configurations. The simulator was written in Visual C++ using the MFC architecture. The simulator includes very detailed functionality with respect to actual circuit operation. Some of the features include: a configurable input signal to inject into the circuit, the ability to insert random clock jitter of various amounts to the entire circuit, a configurable quantizer that can be switched from single bit to multi bit, balanced mode to 2's complement mode, and has the ability to add random quantization step errors. This paper begins with a literature review that describes the journal articles and books used as reference during the creation of the simulator. The paper then describes specifics of the simulator design and its functionality. All aspects of the simulator's operation are addressed. The paper also includes several examples of the simulator's capabilities of evaluating the given sigma delta data converter circuits.
