D.C. Electrothermal Hybrid BJT Model for SPICE

  • Janusz Zarębski

SPICE — built-in models are the isothermal models with the temperature as a parameter. Electrothermal interactions caused that the device (junction) temperature changes due to changes of dissipated power. In the paper the new BJT electrothermal model which includes the thermal effects is proposed. This model is represented by combination of SPICE-built-in isothermal model and any additionaly controlling generators modelling selfheating and some other electrical effects nonmodeled by SPICE.
