Abstract :
The semi-depleted HBT on thin film SOI presents a kink on its electrical characteristics and in particular on the base-collector capacitance. Classical compact models cannot represent this behavior. This paper proposes a new compact formulation of the base-collector junction charge model. Moreover, the impact of this charge on the early effect is shown. Finally, the model is compared to measurements.
