Abstract
In this paper, an improved InP/InGaAs DHBT large-signal model based on the AgilentHBT model is reported. The collector current model is modified for the consideration of hetero-junction effect, and especially, a dispersion current item is put forward and incorporated into the equivalent circuit. The proposed model is implemented by the use of symbolically-defined devices (SDD) in ADS software. The excellent fitting results in DC and s-parametmers indicate that the modified model has better accuracy compared to the conventional one.
