Abstract

The effect of collector lateral scaling on the performance of 300GHz-level SiGe HBTs is investigated. Peak fT and fmax exhibited an initial improvement followed by a degradation with decreasing collector width. Possible causes behind the observed trend are discussed in terms of RC delay and the Kirk effect.
