Abstract
A switched capacitor circuit includes a first capacitor coupled in series with a second capacitor in a first mode of operation across differential output terminals of a circuit. The first capacitor and the second capacitor are coupled in an anti-parallel layout in a second mode of operation. The switched capacitor circuit also includes a third capacitor coupled on a first side to a common node of the first capacitor and the second capacitor. The third capacitor is further coupled on a second side to a current source control voltage in the first mode of operation, and coupled between a bias reference voltage and a common mode reference voltage in the second mode of operation.
