Title: Voltage pump with diode for pre-charge

Abstract: A charge pump system for providing a voltage to a semiconductor device is disclosed. Current charge pumps use a separate pre-charge capacitor and pre-charge circuitry for the boot circuit which provides the gate voltage for the output transistor. The present invention eliminates the need for the separate pre-charge capacitor and pre-charge circuitry by the use of a single diode. The net effect is a more efficient and smaller charge pump circuit.
