Abstract
A regulator circuit for a charge pump voltage generator includes a voltage comparator circuit that performs a voltage comparison between a charge pump output voltage and a reference voltage. A circuit responsive to the voltage comparator circuit conditions a charge pump clocking to the result of the voltage comparison. The voltage comparator circuit includes a sampling circuit for sampling the charge pump output voltage at a sampling rate. A sampling rate control circuit is responsive to the voltage comparisons for controlling the sampling rate according to the result of the voltage comparison.
