A new method of the multiparameter symbolic sensitivity determination based on the equivalent nullor model of active devices and modified Coates flow graph is presented. The proposed method is simple and performs the multiparameter symbolic sensitivity analysis of a synthesized network with respect to various circuit parameters. A special software tool called "HoneySen" has been developed to implement the suggested method. All partial transfer functions and partial sensitivities can be determined, too. Symbolic results for the multiparameter sensitivity of the voltage transfer function for a fourth-order low pass filter is presented. Comparison of the presented method with the Transimpedance method is performed.

In this paper we describe a new method for obtaining, in symbolic form, the network functions and their small-and large-change sensitivities. Our method is based on the two-port transimpedance concept and the sequence of expressions approach to calculation of matrix determinant. We show that the network functions as well as their sensitivities can be expressed by appropriate transimpedances. Each transimpedance is given by an algebraic sum of at most four elements of the inverse of the circuit's reduced node admittance matrix. In our method the complexity of the sequence of expressions grows linearly with the circuit size. The extra effort required to obtain sensitivities is minimal and, more importantly, independent of the circuit size.
