Abstract :
An analytic solution is obtained for the three-dimensional heat diffusion equation applied to a model for a multifinger power transistor. It predicts that the thermal instability takes place based on localized heating and positive feedback. The condition of thermal stability found by Navon and Miller [1] differs from that encountered in this paper.
