Abstract
A charge pump circuit includes first and second capacitors, first and second controllable current generating circuits, and an interconnection circuit. A first terminal of the first controllable current generating circuit is coupled to a first plate of the first capacitor. A first terminal of the second controllable current generating circuit is coupled to a first plate of the second capacitor. During a first operation mode, the first controllable current generating circuit refers to a first control input for selectively providing a first current, and the second controllable current generating circuit refers to a second control input for selectively providing a second current. During a second operation mode, the interconnection circuit couples the first plate of the second capacitor to a first power rail, and couples both of the second plate of the second capacitor and the first plate of the first capacitor to an output terminal.
