Abstract

For relatively strong nonlinear circuits, the conventional variational order reduction method loses efficiency due to the exponentially increased number of inputs and the one-sided projection technique. In this paper, we propose a two-sided projection approach which is capable of matching a much higher number of moments than the one-sided projection method. We show by theoretical analysis and experiments that the two-sided projection method is very efficient for the variational equation model order reduction of nonlinear circuits.
