Abstract
Dual edge modulated charge pumping circuit has an output terminal, a charge pumping conversion circuit, and a dual edge modulated control circuit. The charge pumping conversion circuit has a first capacitor, a second capacitor, and a switch combination circuit. The second capacitor is coupled between the output terminal and a ground potential. The dual edge modulated control circuit controls the switch combination circuit such that the charge pumping conversion circuit operates with a first phase, a second phase, a third phase, and a fourth phase. During the first phase, a first electrode of the first capacitor is floated. During the second phase, the first capacitor is coupled between the ground potential and an input voltage. During the third phase, the first capacitor is coupled between the input voltage and the output terminal. During the fourth phase, the first electrode of the first capacitor is floated.
