Abstract :
This paper presents a methodology to model SiGe HBTs biased in common-emitter and in common-base configurations including the bias-dependent substrate parasitics, which allows determining the more suitable configuration to achieve maximum power gain at different frequency ranges. Model-experiment correlations up to 100 GHz for different bias conditions verify the validity of the proposed circuit representations using the same values for the parameters in both configurations.
