ABSTRACT:
A booster and a voltage detection method thereof are provided herein. The booster includes a charge pump circuit and a voltage detection circuit. The charge pump circuit is controlled by a switching signal to generate an actual voltage according to the basis voltage, wherein the actual voltage is a product of the basis voltage multiplied by a first preset multiplier. The voltage detection circuit is coupled to the charge pump circuit. The voltage detection circuit selects one of a plurality of first multipliers to serve as the first preset multiplier according to a comparison result between the basis voltage and a target voltage, and generates the switching signal corresponding to the first preset multiplier. Therefore, the booster can properly select the first preset multiplier to generate the actual voltage as the basis voltage changes.
