一阶运放模型的开关电容电路精确分析

The Precise Analysis of Switched-Capacitor Circuit with Dominating-Pole Op-Amp Model

本文在文献[1]基础上,以非零主导极点模型代替开关电容(sc)电路中的非理想运放,得到连续和分段恒定激励信号且sc网络拓扑无限制条件下的精确分析方法。文中的计算公式可以系统地在计算机上实现,为计算GB和ω_o对电路产生的影响提供了一条有效的途径。

We consider the nonideal Op-Amp in sc circuit as a dominating model, the precise analytical ways are given for no restriction sc circuit in topological construction and with arbitrary input signals based on reference [1].The systematical calculating formulations can be programed on computer so that an efficient method is obtained to predict the effects of GB and ω0 in sc circuit.
