Abstract :
A scalable large-signal model for heterojunction bipolar transistors (HBTs) is presented in this paper. It allows exact modeling of all transistor parameters from single-finger elementary cells to multifinger power devices. The scaling rules are given in detail. The model includes a new collector description, which accounts for modulation of base-collector capacitance Cjc as well as for base and collector transit times due to temperature effects and high-current injection. The model is verified by comparison with measurements of GaInP/GaAs HBTs
