ABSTRACT:
An active charge pump circuit may include a charge pump circuit, a control circuit, and a charge transfer circuit. The charge pump circuit may generate a charge pumping voltage in response to an active enable signal. The control circuit may generate a charge transfer control signal varying between a ground voltage and a boosted power supply voltage that is twice as much as a power supply voltage in response to the active enable signal. The charge transfer circuit may output the charge pumping voltage as an active voltage in response to the charge transfer control signal.
