Abstract

A new method of second-order symbolic sensitivity determination based on the nullor model of active devices is presented. Using modified Coates flow graph all partial transfer functions required are determined. An algorithm for second-order symbolic sensitivity analysis with respect to various circuit parameters appeared not only at one location in the reduced admittance matrix is proposed. The advantage of the method is that, the matrix inversion is not required. An illustrative example on symbolic sensitivity analysis is given.
