Abstract
Voltage regulation in charge pumps. A high voltage generation system includes a charge pump having an output voltage node and a regulated input voltage node. The high voltage generation system also includes a voltage regulator. The voltage regulator includes a capacitive attenuator in electrical communication with the output voltage node. The voltage regulator also includes a comparator in electrical communication with the capacitive attenuator and with a reference voltage source. The voltage regulator further includes a buffer in electrical communication between the comparator and the regulated input voltage node.
