开关电容网络的灵敏度分析

Sensitivity Analysis of Switched-Capacitor Networks

本文给出了一种有效的开关电容网络计算机辅助灵敏度分析方法。这种新方法利用快速数值型算法获得了符号灵敏度函数。根据该算法编制的计算机程序,可以获得两种灵敏度函数:一种是以增量作为变量的大参量变化灵敏度,另一种是以元件参数本身作为变量的相对灵敏度函数。本文还导出SC网络传输极点及其灵敏度的计算法,最后给出两个计算实例。

An efficient computer method for obtaining sensitivity function of linear SC circuits is presented. The new method uses fast numerical-type algorithms to determine the symbolic sensitivity function. Large change sensitivity function in terms of increments to the nominal values of elements and sensitivity function in terms of element value themselves can be obtained in the actual program. The method can also calculate the poles and their sensitivities of a SC circuit. Two examples are included to illustrate the capabilities of the new method.
