Abstract

In this paper we introduce an approach for parameter controlled symbolic analysis of nonlinear analog circuits. Based on a state-of-the-art algorithm, it enables the removal of specific circuit parameters from a symbolic circuit description, given as a set of nonlinear differential algebraic equations (DAEs). During the removal, singularities are considered, which includes structural changes of the set of DAEs. The feasibility of our approach is shown by several circuit examples
