Abstract
A new direct extraction method for the determination of the parasitic capacitances of HEMTs is presented in this article. This method is based on a physically meaningful depletion-layer model and the theoretical analysis of the two-port network for the pinch-off cold FETs. The main advantage of this approach is that parasitic capacitance Cpg, Cpd, and Cpdg can be extracted under different pinch-off conditions. Good agreement is obtained between modeled and measured results for 2 × 20 μm gate width HEMT (number of gate fingers × unit gate width).
