Design of Low Power and Low Area Passive Sigma Delta Modulators for Audio Applications
by David Fouto and Nuno Paulino
This book presents the study, design, modulation, optimization and implementation of low power, passive DT- Ms for use in audio applications. The high gain and bandwidth amplifier normally used for integration in modulation, is replaced by passive, switched-capacitor branches working under the Ultra Incomplete Settling (UIS) condition, leading to a reduction of the consumed power. The authors describe a design process that uses high level models and an optimization process based in genetic algorithms to achieve the desired performance.
