Abstract
A charge pumping apparatus in accordance with an embodiment may include a charge pump output voltage detector, a pump oscillator, and a charge pump switching controller. The charge pump output voltage detector may detect a charge pump output voltage, and may selectively output an enable signal according to the detected charge pump output voltage. The pump oscillator may output an oscillation signal during a period of time when the enable signal is activated. The charge pump switching controller may selectively operate one of a first pump and a second pump according to a predetermined stabilization time, the enable signal, and the oscillation signal.
