Abstract :
In this paper, we present a~model order reduction approach for nonlinear circuit equations with a~small number of nonlinear elements. This approach is based on the decoupling of linear and nonlinear subcircuits and reducing the linear part using balancing-related model reduction techniques. The efficiency and applicability of the proposed model reduction approach is demonstrated on numerical examples.
