MOSFET Modeling in SPICE and SIMPLIS

SPICE

SIMPLIS

  • Uses non-linear devices, such as diodes to model non-linear capacitance
  • Gate, Source, and Drain lead inductances may be included
  • Model used "as is" in the SPICE simulation, without interpretation
  • Model is not parameterized and is a "Black Box", model behavior varies widely from vendor to vendor
  • Uses Picewise Linear (PWL) models, such as a PWL capacitor to model a non-linear capacitance
  • No parasitic package inductances (have to add externally)
  • SPICE model is simulated in SIMetrix and curve fit to a parameterized PWL model
  • Model is parameterized and well documented
