This paper examines certain aspects of the base resistance model of HiCUM (High Current Model) to address convergence problems seen during 2-tone distortion simulations of SiGe HBTs. Here, we propose some changes to the model implementation and incorporate them in ADS simulator. This resulted in excellent agreement between the inter-modulation distortion measurements and the model.
