  • Abstract
    In this paper, the anomalous dip in scattering parameters S12 of SiGe HBTs is explained quantitatively for the first time. It was found that under constant collector-emitter voltage (VCE), an increase of base current (which corresponds to an increase of base-emitter capacitance (Cπ) enhances the anomalous dip.
