Frequency Domain-Based Method for a Two-Port Nonlinear Quasi-Static Model Extraction from Large-Signal Waveforms

A method for separating the conduction and displacement current components out of quasi-static nonlinear current sources controlled by two variables is described herein. The method is based on a frequency domain formulation and has been tested by analysing a simple nonlinear current model. A distinctive characteristic of the method is that it does not require any integration of incremental capacitances.
