Abstract
A charge pump is regulated based up its output level. The regulation circuitry adjusts the frequency of the pump's clock based on feedback from pump's output. The pump's clock signal is generated by an oscillator whose frequency depends on a reference voltage level. The reference voltage level is dependent upon a regulation signal. In an example, a transistor whose gate is controlled by the regulation level is part of a series of elements in voltage divider, where the reference value is taken from a node of the divider.
