Abstract

A first analog block includes a first plurality of switched capacitors and a second analog block includes a second plurality of switched capacitors. A switch associated with the first plurality of switched capacitors as well as a switch associated with the second plurality of switched capacitors may be configured based on one or more analog functions. The configuring of the first analog and the second analog block may include the configuring of the switch associated with the first plurality of switched capacitors when the analog function is associated with a first single ended signal and the configuring of both the switch associated with the first plurality of switched capacitors and the switch associated with the second plurality of switched capacitors when the analog function is associated with a differential signal.
