Abstract :
An empirical self-heating SPICE MOSFET model which accurately portrays the vertical DMOS power MOSFET electrical and thermal responses is presented. This macro-model implementation is the culmination of years of evolution in MOSFET modeling. This new version brings together the thermal and the electrical models of a VDMOS MOSFET. The existing electrical model [2], [3] is highly accurate and is recognized in the industry. The sequence of the model calibration procedure using parametric data is described. Simulation response of the new self-heating MOSFET model track the dynamic thermal response and is independent of SPICE´s global temperature definition.
