Patent ID: 8482340

Claim:
Charge pump circuitry comprising: (a) master charge pump circuitry including 1) master voltage multiplier circuitry for producing a first unregulated voltage and associated first regulating circuitry for regulating the first unregulated voltage to produce a first regulated voltage, and 2) master pumping circuitry for boosting the first regulated voltage to produce a boosted, unregulated voltage; (b) slave charge pump circuitry including 1) slave voltage multiplier circuitry for producing a second unregulated voltage and associated second regulating circuitry for regulating the second unregulated voltage to produce a second regulated voltage, and 2) slave pumping circuitry for boosting the second regulated voltage to produce a boosted control voltage; (c) third regulating circuitry coupled to regulate the boosted, unregulated voltage in response to the boosted control voltage to produce a boosted, regulated, low-noise voltage; and (d) feedback circuitry coupled between the boosted, regulated, low-noise voltage and the second regulating circuitry to control regulation of the boosted control voltage in accordance with a predetermined reference voltage.
