Nonlinear macromodeling using model order reduction

Automatic reduced order macromodeling of nonlinear circuits is an important problem in design automation. Macromodeling methods based on model order reduction are frequency domain techniques limited to linear circuits. In this paper, a time domain model order reduction method suitable for macromodeling nonlinear circuits is presented. This approach can be completely automated, and is independent of the type of nonlinear circuit to be macromodeled.
