An SOI MOSFET model for circuit simulators considering nonlinear dynamic self-heating

Modeling of the self-heating effect in SOI MOSFETs recently led to static and small-signal models of this device. Nevertheless, large-signal models taking into account this effect are not available yet. We fill this gap by presenting a large-signal electrothermal model of the SOI MOSFET for the simulator SPICE. The whole model is formulated as a set of algebraical and partial differential equations which is converted automatically by the model translator MEXEL into a SPICE3 netlist. The dynamics of the self-heating process are shown by several simulations.
