CMOS Sigma-Delta Converters (PDF)

A comprehensive overview of Sigma-Delta Analog-to-Digital
Converters (ADCs) and a practical guide to their design in
nano-scale CMOS for optimal performance.

This book presents a systematic and comprehensive compilation of
sigma-delta converter operating principles, the new advances in
architectures and circuits, design methodologies and practical
considerations - going from system-level specifications to
silicon integration, packaging and measurements, with emphasis on
nanometer CMOS implementation. The book emphasizes practical design
issues - from high-level behavioural modelling in
MATLAB/SIMULINK, to circuit-level implementation in Cadence Design
FrameWork II. As well as being a comprehensive reference to the
theory, the book is also unique in that it gives special importance
on practical issues, giving a detailed description of the different
steps that constitute the whole design flow of sigma-delta ADCs.


The book begins with an introductory survey of sigma-delta
modulators, their fundamentals architectures and synthesis methods
covered in Chapter 1. In Chapter 2, the effect of main circuit
error mechanisms is analysed, providing the necessary understanding
of the main practical issues affecting the performance of
sigma-delta modulators. The knowledge derived from the first two
chapters is presented in the book as an essential part of the
systematic top-down/bottom-up synthesis methodology of sigma-delta
modulators described in Chapter 3, where a time-domain behavioural
simulator named SIMSIDES is described and applied to the high-level
design and verification of sigma-delta ADCs. Chapter 4 moves
farther down from system-level to the circuit and physical level,
providing a number of design recommendations and practical recipes
to complete the design flow of sigma-delta modulators. To conclude
the book, Chapter 5 gives an overview of the state-of-the-art
sigma-delta ADCs, which are exhaustively analysed in order to
extract practical design guidelines and to identify the incoming
trends, design challenges as well as practical solutions proposed
by cutting-edge designs.
