Abstract
A switched capacitance circuit selectively provides a capacitance across first and second output nodes in response to a selection control signal. The switched capacitance circuit may include a first capacitor coupled between the first output node and a mid-node, a second capacitor coupled between the second output node and the mid-node, and a switching circuit. The switching circuit is configured to switch the first and second capacitors in response to the selection control signal and to provide a bias voltage at the mid-node in response to the selection control signal.
