Abstract

Analog simulation methodologies for the generation of macromodels of analog functional blocks, as reported in literature, are of limited use in practical circuit simulation due to frequent accuracy and efficiency problems. In this paper, a new approach to model the behavior of nonlinear functional blocks is proposed. The approach is based upon the principles of systems theory. The outlined methodology supports the mapping of models from component into behavioral level. The nonlinearity of complex analog modules is reflected efficiently while the electrical signals are maintained.
