Small-Versus Large-Signal Extraction of Charge Models of Microwave FETs
Artikel i vetenskaplig tidskrift, 2014

In this letter we extract the parameters of the charge equations of a microwave transistor nonlinear model which is available in commercial CAD tools. In particular, the charge model parameters are extracted starting from small- and large-signal measurements. A better accuracy can be achieved when using large-signal measurements since the model parameters are obtained from experimental data which better reproduce the actual operating condition of the device under test. An advanced 0.15 x 300 mu m(2) pHEMT in GaAs technology, aimed at cold-FET mixer design, is considered as case study.
