Patent ID: 8278720

Claim:
A switching device having an input node, an output node, and a control node, the device comprising: a semiconductor substrate having a first side and a second side opposite the first side; a ground plane disposed on the first side of the semiconductor substrate; a mesa disposed on the second side of the semiconductor substrate, the mesa comprising normally-conductive semiconductor material; an isolation region substantially surrounding the mesa; a field effect transistor (FET) disposed on the mesa above the semiconductor substrate, the FET having an input terminal connected to the input node, an output terminal connected to the output node, and a gate; a first resistor in series with a capacitor, the series combination of the first resistor and the capacitor being disposed on the mesa and being connected between the output terminal of the FET and the gate of the FET; and a second resistor connected in series between the control node and the gate of the FET, the second resistor being disposed on the mesa.
