Design of Low Power and Low Area Passive Sigma Delta Modulators for Audio Applications

This book presents the study, design, modulation, optimization and implementation of low power, passive DT-SigmaDeltaMs for use in audio applications. The high gain and bandwidth amplifier normally used for integration in SigmaDelta 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.

List of contents

Summary

This book presents the study, design, modulation, optimization and implementation of low power, passive DT-ΣΔMs for use in audio applications. The high gain and bandwidth amplifier normally used for integration in ΣΔ 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.
