Abstract

An accurate direct extraction method of small-signal model parameters for the heterojunction bipolar transistor (HBT) is presented. The extraction procedure, based on the hyper-PI equivalent circuit for the HBT, used a set of S-parameters measured under different bias conditions. An experimental verification on an InGaP/GaAs HBT device with 2 fingers and 2 μm×20 μm emitter area was carried out, and excellent results were obtained up to 20 GHz. The fitting residual error with extracted data for three different bias points over DC-20 GHz, was less than 6%.
