摘要:	In this paper, the anomalous dip in scattering parameters S(12) of SiGe HBTs is explained quantitatively for the first time. It was found that under constant collector-emitter voltage (V(CE)), an increase of base current (which corresponds to an increase of base-emitter capacitance (C pi) enhances the anomalous dip.
