  • Abstract
    A new technique for extracting bias-dependent drain resistance Rd in microwave FETs is proposed. Solving a set of equations for the new FET internal equivalent circuit, the analytical formula for bias-dependent Rd value is derived. The dependence of Rd on bias voltages is obtained for 0.15 um GaN HEMT on SiC substrate. The use of bias-dependent Rd in linear and nonlinear FET models leads to improving the modeling accuracy of the FET S-parameter, IV-characteristics, and output power.
