| 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. |
