Abstract
A charge pump filtering circuit includes a charge pump circuit and a filter circuit. The charge pump circuit includes a first switch and a second switch. The first switch and the second switch are coupled at a first node and are coupled between a power terminal and a ground terminal. The filter circuit includes a first capacitor, a second capacitor, and a first voltage switching circuit. The first capacitor is coupled between the first node and the ground terminal. The second capacitor is coupled between the first voltage switching circuit and the first node.
