Abstract

Some new models for nonlinear capacitors and nonlinear inductors built with SPICE-like element primitives are presented
here. They have the advantage that they can be used for simulation in SPICE of those circuits which contain nonlinear
capacitors controlled either in voltage or in charge, and nonlinear inductors controlled either in current or in flux. These
SPICE-like models contain current sources whose controlling variables are charge time-derivative and sources whose
controlling variables are flux time-derivative. For validation, the models are included in nonlinear circuits; their behavior is
studied by simulation using two different simulators and the results are compared.
