High voltage generator circuit with ripple stabilization function

摘要

The present invention disclosed herein is a high voltage generator circuit. The high voltage generator circuit includes a charge pump and a pump clock signal generator. The pump clock signal is gated to the charge pump when the high voltage is below a target voltage. After the high voltage reaches the target voltage, the high voltage cyclically falls below the target voltage. After the high voltage reaches the target voltage, a pump clock generator block circuit limits the transmission of the pump clock signal so that only N clock signals are gate to the charge pump each cycle, where N is the number one or greater.
