ABSTRACT:
A voltage generator includes a charge pump, a voltage dividing circuit, and a comparator. The charge pump can output a high voltage. The dividing circuit includes a plurality of resistors and at least one switch. The dividing circuit can generate a first divided voltage of the high voltage when the switch is turned on and a second divided voltage of the high voltage when the switch is turned off. An output signal of the comparator can control the switch and the charge pump. The dividing circuit and the comparator form a feedback loop so that the response speed of the comparator can be increased and the ripples of the high voltage outputted from the charge pump can be decreased.
