Abstract
A tunable depletion diode is provided. Within this depletion diode, there is a depletion mode transistor that is coupled to the anode terminal at its gate and the cathode terminal at its drain. A diode is coupled between the source of the depletion mode transistor and the anode terminal, and a variable capacitor is coupled between the source of the depletion mode transistor and the anode terminal, where the capacitance of the variable capacitor is controls the reverse recovery time of the tunable depletion diode.
