This paper presents the first simulation of the minimum noise figure of a heterojunction bipolar transistor based on Shockley’s impedance field method and the hydrodynamic model. The hydrodynamic model and the impedance field method are described as well as the optimization procedure for calculating the minimum noise figure from Y-parameters and noise voltage spectra. In addition to the minimum noise figure, DC and AC properties are simulated and compared to measurements in order to verify the new approach. Finally the spatial origin of noise is determined by simulation.
