CMOS Cascade Sigma-Delta Modulators for Sensors and Telecom: Error
Analysis and Practical Design presents architectures, circuits,
models, methods and practical considerations for the design of
high-performance low-pass switched-capacitor (SC) sigma-delta A/D
interfaces for mixed-signal CMOS ASICs. Main focus is on cascade
architectures, although considerations pertaining to circuits and error
analysis are general and hence valid for other architectures.
The book differs from others in the complete, in-depth coverage of SC
circuit errors, in the detailed elaboration and description of practical
design plan, and in the thorough presentation of considerations leading
to practical high-performance designs. Another differentiating feature
of this book is the coverage into a unified description of largely
different application areas. On the one hand, sensor front-ends, where
the limiting factor is thermal noise. On the other, wire-line telecom
front-ends, where the limiting factor is linked to the dynamic behavior
of the building blocks.
The book starts with a tutorial presentation of the fundamentals of
low-pass sigma-delta modulators, their applications, and their most
common architectures. This presentation is both complete and
comprehensive. It then presents an exhaustive analysis of SC circuit
errors with a twofold outcome. On the one hand, compact expressions are
derived to support design plans and quick top-down design. On the other,
detailed behavioral models are presented to support accurate
verification. This set of models allow the designer to determine the
required specifications for the different modulator building blocks and
form the basis of a systematic design approach. The book is completed in
subsequent chapters with the detailed presentation of three
high-performance modulator ICs: the first two are intended for DSL-like
applications, whereas the third one is intended for automotive sensors.
CMOS Cascade Sigma-Delta Modulators for Sensors and Telecom: Error
Analysis and Practical Design contains highly valuable information
that is structured to give the reader the necessary insight on how to
design SC sigma-delta modulators. In this sense, the book is intended
for a large audience: from mixed-signal designers who want to optimize
and to shorten the design cycle of sigma-delta modulators with
challenging specifications, to non-experienced readers who want a
comprehensive and practical description of sigma-delta design and SC
errors.
