SAUCES：模拟电路设计的灵敏度分析程序

本文提出了符号电路转移函数对每个电路元件的灵敏度以及符号电路转移函数的零、极点灵敏度的简单化导方法,并描述了以这些方法为基础而编制的电路灵敏度分析程序——SAUCES。该程序能够以有限的计算时间和存储量生成一个简化的符号电路函数来进行符号电路分析,并利用符号电路分析的结果采用符号或数字来计算模拟电路的灵敏度。本文给出了一个计算实例以说明怎样应用 SAUCES 程序来改进电路设计,该程序的输出对设计者修正/改进电路设计是很有价值的。

SAUCES:A Sensitivity Analysis Program for Analog Circuit Design

The simple methods to derive the sensitivity of a symbolic circuit transfer function with respect to each circuit element and the sensitivity of zeros and poles symbolically for the circuit transfer function are presented. A circuit sens- itivity analysis program called SAUCES based on these is described. This pro- gram can generate a simplified symbolic circuit function with limited CPU time and memory space to carry out symbolic circuit analysis. Using the results of symbolic circuit analysis, SAUCES computes. The sensitivity of an analog circuit either symbolically or numerically. An example is given to show how SAUCES can be used to improve circuit design. The outputs of this program are valuable for designers to correct/improve a circuit design.
