Abstract:
1. An integrated group III-nitride device, comprising: an enhancement-mode high electron mobility transistor (E-HEMT) comprising a first source electrode, a first drain electrode and a first gate electrode; and a depletion-mode high electron mobility transistor (D-HEMT) comprising a second source electrode, a second drain electrode and a second gate electrode, wherein the first gate electrode is in series with the second source electrode, wherein the second gate electrode is connected to the second source electrode and the first gate electrode, wherein a gate voltage of the E-HEMT is driven by application of an input bias voltage to the second drain electrode, and wherein a current at the first gate electrode generated in response to the application of the input bias voltage to the second drain electrode is clamped at a saturation current of the D-HEMT.
