  • DAC-based voltage regulator for flash memory array
    Patent number: 6771200
    Abstract: A DAC-based voltage regulator system for a non-volatile memory device comprises a charge pump circuit having an enable input and a voltage output node. A voltage-to-current converter has an input coupled to the voltage output node and an output coupled to a virtual ground node. A current source is coupled to the virtual ground node and sinks one of a plurality of currents in response to states of a plurality of digital input signals. A transconductance amplifier has an inverting input at the virtual ground node, a non-inverting input coupled to a reference voltage potential, and an output. A comparator has a first input coupled to the output of the transconductance amplifier, a second input coupled to a reference voltage potential, and an output coupled to the enable input of said charge pump.
