摘要

提出了一种基于有源器件零值模型的综合网络多参数灵敏度分析算法。采用改进的科茨流图对其进行了简化。该方法获得了电路中参数对传输系数影响的附加信息，得到了所有的偏传递函数及其乘积。最后给出了用跨阻运算放大器模型对通用滤波器进行符号分析的实例，说明了所提出的符号方法在基于nullor模型的多参数灵敏度分析中的有效性。

Multiparameter symbolic sensitivity analysis by using nullor model and Coates flow graphs

An algorithm for multiparameter sensitivity analysis of a synthesized network based on a nullor model of active devices is implemented. It is simplified by using the modified Coates flow-graph. Due to the suggested method, additional information for parameter influence upon transmission coefficients in the circuit is obtained, all partial transfer functions and their products can be found. An example on symbolic analysis of universal filter with the operational transresistance amplifier model is given in order to show the usefulness of the proposed symbolic method for multiparameter sensitivity analysis based on the nullor model.
