高阶开关电容滤波器设计

Design of High-order Switchd-capacitor Filter

开关电容滤波器因其外围简单,性能良好而在语音信号处理系统令应用广泛.本文将着重阐述一种简单有效的高价开关电容滤波器综合方法.同时介绍应用于其中的高性能串接型CMOS运算放大器单元.

Due to few outside components needed and high performance, CMOS switched-capeitor filters are used widely on the realization of volcebod frequeney signat-process circuit. Thepaper offers an easy and effechve mathod to design a highperformace switohed-capeitor filter. On the sam. time, this paper brings a kind of new CMOS amplifier used in switched-capacitor filters.
