摘要：A booster and a voltage detection method thereof are provided herein. Thebooster includes a charge pump circuit and a voltage detection circuit. The charge pumpcircuit 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 afirst 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 thefirst preset multiplier according to a comparison result between the basis voltage and atarget voltage, and generates the switching signal corresponding to the first presetmultiplier. Therefore, the booster can properly select the first preset multiplier togenerate the actual voltage as the basis voltage changes.
