Implementation of a scalable and statistical VBIC model for large-signal and intermodulation distortion analysis of SiGe HBTs

This work examines for the first time the utility of the VBIC model for the analysis of 2-tone intermodulation distortion behavior of SiGe HBTs. The model takes into account all important effects for accurate modeling of large signal behavior including self-heating, weak-avalanche multiplication, quasi-saturation effects, and all device capacitances. Periodic-Steady State and Harmonic Balance simulations are performed and the model is validated by load-pull measurements.
