用信号流图分析开关电容网络

大型开关电容（SC）网络往往是由许多SC网络级联而成的,而级联之前要对SC子网络进行优化设计,就必须得到子网络的网络函数表达式。本文介绍了一种通过观察SC网络的拓扑结构,直接得到网络的信号流图（SFG）,从而得到所需要的网络数的方法。

Direct analysis of switched_capacitor networks with signal flow graphs

The design of large switched_capacitor (SC) networks is very often modular. The building blocks must first be optimized before they can be connected together into a large circuit. Optimizing the building blocks generally requires closed_form expressions for transfer function. This paper presents a method for direct closed_form analysis of SC networks with signal_flow graph(SFG) techniques. It permits the SFG of a SC network to be drawn directly by inspection. Arbitrary network functions can then be obtained by using SFG theory.
