Overview
- Enables the design of a Sigma Delta modulator, an oversampling converter, for audio and biomedical applications
- Describes methods for minimizing both circuit area and power dissipation
- Presents techniques that use passive integrators based on the ultra-incomplete settling concept, employing a switched capacitor topology, eliminating the need for a high gain amplifier

About this book
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.
