摘要

基于两个全通滤波器并联的开关电容器结构的极低灵敏度特性最近已被计算机模拟证明。本文介绍了一种基于该技术的SC视频滤波器的集成电路设计，并给出了在实验室中获得的实验结果来验证该方法的有效性。提出了一种基于全通滤波器段并联的SC滤波器传递函数测试方法。

A low sensitivity switched-capacitor filter design with testability features

The very low sensitivity properties of a switched-capacitor structure based on a parallel connection of two allpass filters has been recently demonstrated by computer simulations. This paper presents the IC design of an SC video filter using this technique, and shows experimental results obtained in the laboratory to verify the validity of the proposed approach. A procedure for testing the transfer function of SC filters based on a parallel connection of allpass filter sections is presented.
