Abstract
The influence of doping profile on stability characteristics of SiGe HBTs in both common-emitter and common-base configurations is studied for the first time. It is found that the base doping concentration has a strong influence on the stability characteristics of the common-base configuration. An unconditional stability operation condition for the common-base SiGe HBTs can be potentially realized over the entire amplification frequency range by employing sufficiently high base-doping concentrations
