Abstract
A voltage control device includes a charge pump, a driving circuit, and a control circuit. The charge pump provides a first voltage. The driving circuit is coupled to the charge pump, and receives the first voltage and a reference voltage. The driving circuit outputs a driving signal according to an input signal, the first voltage and the reference voltage. The control circuit is coupled to the charge pump and the driving circuit. Before the first voltage reaches a threshold level, the control circuit adjusts the reference voltage to increase the voltage gap between the first voltage and the reference voltage.
