PSPICE灵敏度分析在优化电路设计中的应用

The Application of PSPICES Sensibility Analysis in the Improvement of the Designs for Circuit

电路优化设计是将最优化方法与电路ＣＡＤ分析程序结合起来而实现的．本文介绍在给定电路拓扑结构和电路元件初值的前提下，利用ＰＳＰＩＣＥ的灵敏度分析来计算电路的状态和特性，根据分析结果是否符合电路性能指标要求，在计算机屏幕上调整、修改电路元件参数，使电路特性达到设计要求。

The realization of the improvement of the designs for circuit is achieved by operating the analysis procedure of CAD in the most improved and effective methods. The purpose of fhis article is on how to calculate the state and the characteristic of circuit by using the PSPICES sensibility analysis under the given infamation of the diagram of principle of the analysed circuit and the original value of the element and how to fulfil rhe design requirements and to achieve the improvement of the characteristics of circuit by adjusting and correcting the reference data of the elements on the computers screen according to the imformation between the analysis results of PSPICE and the funtional index of circuit.
