Abstract:An accurate and broadband method for heterojunction bipolar transistors (HBTs) small-signal model parameters is presented in this article. This method differs from previous ones by extracting the equivalent-circuit parameters without using a special test structure or global numerical optimization techniques. The main advantage of this method is that a unique and physically meaningful set of intrinsic parameters is extracted from impedance and admittance representation of the measured S-parameters in the freque… Show more
