JFET/MESFET TRIQUINT Models (Level=5 and level=7)

Introduction

Until now, SmartSpice has supported the TriQuint model designated TOM using the Level=5 model parameter. SmartSpice now supports the TriQuint-2 MESFET model designated TOM-2. This model is accessible as a standard MESFET model, using the Level=7 model parameter. It is an incremental improvement based on TriQuint?s original MESFET model. All current analyses are currently supported (dc, ac, transient and noise).

Physical Effects

Refinements to improve accuracy in the knee and subthreshold region have been added. Particular attention has been given to temperature effects. TOM-2 retains the desirable features of TOM-1 while improving performance in the subthreshold characteristics near the cut-off and knee regions. Additional temperature coefficients are included relating to the drain current and major deficiencies in the behavior of the capacitance as a function of temperature have been corrected.
