Titel:
Electro-Thermal Large-Signal Modeling of SiGe HBTs 
Abstract:
The temperature dependence of double-mesa SiGe HBTs is investigated. The different bandgaps of the hetero junctions cause the characteristic temperature behavior of HBTs. A straight forward method to extract the effective bandgaps of base, emitter and collector is explained. The thermal resistance is calculated and a dependence on temperature and on dissipated power similar to GaAs is found. For modeling purposes, as a first approximation, a constant value for the thermal resistance can be assum...    »
