Abstract
An initialization device for a charge pump includes a driving circuit and a bias voltage circuit. The driving circuit is between two power supply nodes. The driving circuit includes a first node configured to be coupled to an output electrode of a capacitor in the charge pump. The bias voltage circuit is coupled to the two power supply nodes. The bias voltage circuit includes a second node coupled to a control terminal of the driving circuit. In response to an applied initialization signal, the bias voltage circuit is configured to output a bias voltage to the second node. The bias voltage has at least two levels that correspond to levels of the applied initialization signal. In response to the bias voltage, the driving circuit is configured to output an output signal having at least two levels that correspond to the at least two levels of the bias voltage.
