Parameter Extraction for Simplified RF NMOSFET Equivalent Circuit using Spice

Abstract

In the paper, a parameter extraction approach is proposed to a simplified small-signal NMOSFET equivalent circuit utilizing Cadence PSpice circuit simulator. A direct extraction procedure is realized based on the two-port Y-parameters. The computer realization of the developed extraction procedure is performed using parameterization of the model. Based on postprocessing in the graphical analyzer Probe utilizing corresponding macrodefinitions, the two-port Y-parameters are calculated. Verification of the extraction methodology is made by comparing the simulated and experimental results for the Y-parameters.
