Patent ID: 10388650

Abstract:
The disclosure belongs to the technical field of semiconductor power devices, specifically relates to a semi-floating-gate power device, and comprises the gallium nitride high-electron-mobility transistor, the diode and the capacitor; the anode of the diode is connected with the gate of the gallium nitride high-electron-mobility transistor and the cathode of the diode is connected with the source or the channel area of the gallium nitride high-electron-mobility transistor; one end of the capacitor is connected with the gate of the gallium nitride high-electron-mobility transistor and the other end of the capacitor is connected with the external voltage signal. The semi-floating-gate power device has a simple structure, is easy to manufacture, adapts to high-voltage and high-speed operation and has very high reliability, can increase the threshold voltage of the gallium nitride high-electron-mobility transistor in the working state, so that the transistor can serve as the power switch tube better.
