Abstract

The design of high frequency large-signal active devices depends heavily upon the accuracy of the models used by CAD programs. Traditionally, these models have either been physics or equivalent-circuit based, and this paper presents an alternative approach where measured large-signal data is directly incorporated into the design environment. This approach ensures an accurate representation of the device under large-signal operating conditions and also offers the ability to validate any matching solutions developed before the physical MMIC is realised.
