Abstract

A circuit includes a switched capacitor circuit and a voltage generator circuit. The switched capacitor circuit includes first, second, third, and fourth switches and first and second capacitors. The first capacitor has first and second terminals, the first terminal coupled to the first switch. The second capacitor has first and second terminals, the second terminal coupled to the second switch. The third switch has a terminal coupled to the second terminals of the first and second capacitors. The fourth switch has first and second terminals, the first terminal coupled the terminal of the third switch and to the second terminals of the first and second capacitors. The voltage generator circuit has an output coupled to the second terminal of the fourth switch and is configured to provide a common mode output bias voltage at the second terminal of the fourth switch responsive to a common mode input bias voltage.
