Design and thermal analysis of SiGe HBT with segmented emitter fingers and non-uniform segment spacing

Abstract

A novel multi-finger power SiGe heterojunction bipolar transistor (HBT) with segmented emitter fingers and nonuniform segment spacing was proposed to improve the thermal stability. Thermal simulation for a ten-finger power SiGe HBT with novel structure was conducted with ANSYS software. Three-dimensional temperature distribution on emitter fingers was… (More)
