Abstract
Various embodiments for controlling a ramp rate of a high voltage generator circuit such as a charge pump circuit are disclosed. In one embodiment the ramp rate of the output signal is controlled by modulating an amplitude of the oscillating signal at the input of the charge pump circuit. In another embodiment, the ramp rate is controlled by modulating the current loading at the output of the charge pump circuit. In yet another embodiment, the ramp rate of the output signal is controlled by modulating the frequency of the oscillating signal at the input of the charge pump circuit.
