Novel and simple table-based HBT large-signal model

A novel and simple table-based HBT large-signal model is presented. All parameters are tabulated as two- parameter functions. The model accounts for self-heating by allowing ideality factors and saturation currents to be functions of the dissipated power. Small-signal model parameters, systematically extracted from RF S-parameter measurements, are used in conjunction with DC measurements to extract static model parameters characterizing the forward active regime of operation. Such a procedure ensures consistency between small-signal and DC simulations. A 1x10 mum² emitter-area InGaP/GaAs HBT device is used to validate the proposed model.
