Abstract

The power gain of SiGe HBTs with constant total Ge content (strain) but different doping profiles is studied under common-emitter (CE) and common-base (CB) configurations. It is found that CE and CB configurations show different power gain sensitivity on doping concentration and bias condition. The sensitivity of fmax on Ge profile and doping profile is also investigated.
