ABSTRACT:
A circuit for driving a depletion-type JFET comprises a capacitor connected between the gate of the depletion-type JFET and a control signal, and a switch that is controlled by the control signal connected between the gate and source of the depletion-type JFET. The depletion-type JFET is turned on when the control signal is at a high voltage, and is turned off when the control signal is switched to a low voltage. The circuit and its driven depletion-type JFET can be integrated on a single chip to be a new power switch apparatus.
