This book discusses the design of switched-capacitor filters in deep-submicron CMOS technologies. The authors describe several topologies for switched-capacitor filter circuits that do not require high-gain high-bandwidth amplifiers. Readers will also learn two analysis methodologies that can be implemented efficiently in software and integrated into optimization environments for the automation of design for switched-capacitor filters. Although the optimization examples discussed utilize low gain amplifiers, the demonstrated methodologies can also be used for conventional, high-gain high-bandwidth amplifiers. . Enables design of switched-capacitor filters using low gain amplifiers to simplify implementation in advanced CMOS;. Demonstrates fast and accurate analysis methodologies for switched-capacitor filters;. Includes several analysis and optimization examples, validated through electrical simulations.
