Abstract
A driver circuit is disclosed. The driver circuit is configured to generate a drive voltage for driving a bootstrap transistor. The driver circuit includes an input node and an output node, a first circuit including a plurality of switches, a first capacitor and a second capacitor, and a pass gate switch coupled between the output node and the first capacitor. In one aspect, the first circuit, the first and second capacitors and the pass gate switch are arranged to cause an output voltage at the output node to change from a first output voltage to a second output voltage. In another aspect, a resistor is connected between the first capacitor and the second capacitor, and a feedback switch is connected in parallel to the resistor. The feedback switch is turned on in response to a feedback signal, thereby reducing an impedance value of the resistor.
