Abstract
A regulator () for a charge pump () includes a clock amplitude modulator () that changes voltage of a clock signal used in operation of the charge pump in response to changes in magnitude of output voltage of the change pump. The clock amplitude modulator is powered by an output of an auxiliary circuit (). The output of the auxiliary circuit is at a higher voltage than an input voltage of the charge pump. A maximum amplitude of the voltage of the clock signal is higher than the input voltage of the charge pump.
