Abstract :
We present the first systematic experimental and modeling results of corner frequency (f/sub C/) and the corner frequency to cut-off frequency ratio (f/sub C//f/sub T/) for SiGe HBTs in a commercial SiGe RF technology. The f/sub C//f/sub T/ ratio is examined as a function of biasing current for SiGe HBTs featuring multiple collector doping profiles (breakdown voltages) and multiple SiGe profiles.
