Oversampled A/D converters have become very popular in recent years.
Some of their advantages include relaxed requirements for anti-alias
filters, relaxed requirements for component matching, high resolution
and compatibility with digital VLSI technology. There is a significant
amount of literature discussing the principle, theory and implementation
of various oversampled converters. Such converters are likely to
continue to proliferate in the foreseeable future. Additionally, more
recently there has been great interest in low voltage and low power
circuit design. New design techniques have been proposed for both the
digital domain and the analog domain. Both trends point to the
importance of the low-power design of oversampled A/D converters.
Unfortunately, there has been no systematic study of the optimal design
of modulators for oversampled converters. Design has generally focused
on new architectures with little attention being paid to optimization.
The goal of Design of Modulators for Oversampled Converters is to
develop a methodology for the optimal design of modulators in
oversampled converters. The primary focus of the presentation is on
minimizing power consumption and understanding and limiting the
nonlinearities that result in such converters.
Design of Modulators for Oversampled Converters offers a quantitative
justification for the various design tradeoffs and serves as a guide for
designing low-power highly linear oversampled converters. Design of
Modulators for Oversampled Converters will serve as a valuable guide
for circuit design practitioners, university researchers and graduate
students who are interested in this fast-moving area.
