High performance power MOSFET SPICE macromodel

This paper presents a new method of SPICE, behavioral macromodeling of power MOSFETs, that describes device´s internal static equations directly with “in line equation” controlled voltage and current sources and the nonlinear interelectrode capacitances are piece-wise-linear approximated with “table defined” controlled sources. The thermal variation of model parameters are equally considered. This new macromodel gives a higher accuracy of static and dynamic power MOSFET description, with no convergence problems and with a reasonable analysis time
