Abstract :
A simple experimental procedure is proposed to determine the separate ranges of reverse collector-base bias where neutral base recombination and avalanche breakdown, respectively, dominate base current reduction in silicon germanium heterojunction bipolar transistors (SiGe HBTs) which exhibit significant neutral base recombination
