  • On chip multiple voltage generation using a charge pump and plural feedback sense circuits
    Patent number: 4752699
    Abstract: A level selectable FET voltage generation system is described. The system includes a single charge pump controlled by multiple feedback paths and a powerdown circuit. Each feedback path contains a capacitor divider network, a sense amplifier with a compensating voltage reference and a timer which periodically resets the capacitor divider network to insure sensing accuracy. The powerdown circuit and a selected feedback path provides a desired voltage level at the output of the charge pump.
