Abstract
An internal supply generator includes a charge pump, at least one regulator and a pump controller. The charge pump generates a charge pump signal whose voltage is higher than an input supply voltage. Each regulator produces a generally stable internal supply from the charge pump signal. The pump controller activates the charge pump whenever the charge pump signal falls to within a predetermined voltage of the voltage level of one of the internal supplies.
