Abstract

The small-signal equivalent circuit of AlGaN/GaN high electron-mobility transistors is discussed. A new modeling procedure is introduced in this paper that does not bias the device at a untenable high gate voltage in order to extract the parasitic inductance and resistance. Simulated results show good agreement with measurements up to 40 GHz.
