Abstract
This paper describes a modeling approach for Vitesse VIP2 300 GHz InP/InGaAs DHBT technology, including the nonlinear effects in base-collector region covering current blocking, velocity modulation and self-heating. Model is verified in terms of single devices and integrated circuits. Good model fitting to measured DC and s-parameters data from single HBTs is achieved, and several circuits based on Gilbert multiplier are designed for the purposes of model validation and high-speed applications. Nonlinear properties of these circuits are measured and compared with the simulation results from different bipolar transistor models. The variable gain amplifier reported in this paper achieves the highest gain-bandwidth product of over 520 GHz under the limitation of measurement capability.
