摘要
大型开关电容 （ Ｓ Ｃ） 网络往往是由许多 Ｓ Ｃ 子网络级联而成的， 而级联之前要对 Ｓ Ｃ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 Ｓ Ｃ 网络的拓扑结构， 直接得到网络的信号流图 （ Ｓ Ｆ Ｇ） ， 从而得到所需要的网络函数的方法。
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.
