Comparison of HEMT non‐linear model extraction approaches based on small signal and on large signal measurements

In this paper the extraction of a non‐linear model for a HEMT is undertaken by means of two different approaches. The first approach is the classical procedure that consists of using the small signal data to fully generate a non‐linear model. The second alternative is developed following a different tactics that uses directly the response of the device to a large signal stimulus. Both approaches are compared in terms of required extraction measurements and limits of application. Copyright © 2002 John Wiley & Sons, Ltd.
