Circuit analysis and optimization with automatically derived Volterra kernels

The problem of the symbolic analysis of nonlinear dynamical behaviour in the design of analogue circuits and systems is addressed in this paper. Where classical circuit and system level simulators basically rely on numerical simulations for that analysis, a symbolical method is considered here. This method is based on the Volterra Series (VS). A short introduction on the use of VS in system analysis is given. An implementation of a symbolic system analysis tool in its first stages based on VS is described. Complexity and efficiency of the implemented methods are discussed. An example is given where the implemented analysis tool is used optimise a simple circuit. The results are verified with Spice. Finally, an outlook on the open problems of the current implementation is given
