Abstract
A charge pump and operating method thereof are disclosed. The charge pump includes a first capacitor to a third capacitor and a first switch to a tenth switch. The charge pump is used to receive an input voltage and provide an output voltage to a load capacitor. When the charge pump is operated in a first mode, the charge pump controls the second capacitor failure, the output voltage and the input voltage have opposite electricity and the output voltage is (−½) times the input voltage. When the charge pump is operated in a second mode, the charge pump controls the second capacitor failure, the output voltage and the input voltage have opposite electricity and the output voltage is (−⅔) times the input voltage.
