Two 1-V Fully Differential CMOS Switched-Capacitor Amplifiers

摘要

Two 1-V fully differential CMOS switched-capacitor amplifiers in a standard CMOS 0.35-μm technology are presented. The improved bootstrapped switches are used to allow rail-to-rail signal swing. The circuit design of the major building blocks is described. The performance of these two circuits is demonstrated by experimental results.
