Abstract:
1. An apparatus for providing a regulated output voltage, comprising: a voltage regulator that is arranged to provide the regulated output voltage in response to a boost voltage; a voltage booster that is arranged to selectively distribute charge from a first capacitance circuit to a second capacitance circuit when activated and prevent the distribution of charge from the first capacitance circuit to the second capacitance circuit when deactivated, wherein the boost voltage is associated with the second capacitance circuit such that the boost voltage increases when the voltage booster is activated and decreases when the voltage booster is deactivated; a boost control that is arranged to selectively control the voltage booster in response to a comparison of the boost voltage and the regulated output voltage such that the voltage booster is deactivated when the boost voltage is above the regulated output voltage by a predetermined level; and an oscillator that is arranged to provide a control signal to the voltage booster, wherein operation of the oscillator is unaffected by operation of the boost control, the voltage booster, and the voltage regulator.
