Abstract
The authors report for the first time a time-domain analysis of therma l instability in multifinger heterojunction bipolar transistors (HBT's ). This is based on a transient quasi-three-dimensional (3-D) electrot hermal model that selfconsistently solves the thermal and electrical e quations, This model is designed to evaluate the thermal time constant of GaAs-based power HBT's employing emitter thermal shunt and emitter ballast resistance.
