Voltage converter circuit with depletion transistor and resistive element
A recently granted patent (Publication Number: US11876511B2) discloses a voltage converter circuit that includes a depletion transistor and a resistive element to limit leakage current and provide a turn-on current to a switch. The resistive element is connected between the gate and drain/source terminals of the depletion transistor, generating a negative voltage across it. The circuit effectively controls leakage current flow between voltage rails and regulates the turn-on current based on the pinch-off voltage of the depletion transistor.
Furthermore, the patent also describes a process for limiting leakage current in the voltage converter circuit by flowing current through a path involving the depletion transistor and resistive element. By applying a pinch-off voltage to the depletion transistor, the current is restricted, with the voltage across the resistive element creating a negative voltage between the gate and source terminals of the transistor. This process ensures efficient current limitation based on the resistive element's characteristics and the configuration of the depletion transistor, enhancing the overall performance of the voltage converter circuit.
