Abstract
An apparatus includes a first switch coupled to a first voltage reference and a second switch coupled to a second voltage reference. A third switch is coupled to a first terminal of a first capacitor and a first terminal of a second capacitor. A fourth switch is coupled to a second terminal of the first capacitor and the first terminal of the second capacitor. A fifth switch is coupled to the second terminal of the first capacitor and a first terminal of a third capacitor. A sixth switch is coupled to the first terminal of the first capacitor and the first terminal of the third capacitor. The first switch, the second switch, the third switch, the fourth switch, the fifth switch, and the sixth switch are controlled to maintain a first voltage level at a first output and a second voltage level at a second output.
