Non-Quasi-Static Large-Signal SOI-MOSFET models

Large-signal electro-thermal microwave models for FETs SOI-MOSFETs and HEMTs were developed (Allied Signal) ). Theses models are non-quasi-static, charge-conserving electro-thermal large-signal FET models . These FET models account for self-biasing (parasitic bipolar transistor and IV kink) and self-heating. A table representation using B-Spline is used for its speed and uniqueness of extraction. (Siraj Akhtar, Patrick Roblin)
Figure 1 compares the measured on (PISCES) and fitted isothermal DC I-V characteristics. Figure 2 compares the measured on (PISCES) and predicted transient I-V characteristics. Figures 3-5 compare the measured and predicted power gain and output power fondamental, first and second harmonics, and the power added efficiency all versus input power. Figure 6 shows the temperature measured versus predicted temperature.
