Abstract:
A switched-capacitor circuit is described herein. In accordance with one exemplary embodiment the switched-capacitor circuit includes a first input node and a second input node and an input switch unit. The input switch is connected to the first input node and the second input node and has a first output node and a second output node. A first capacitor is coupled to the first output node of the input switch unit, and a second capacitor is coupled to the second output node of the input switch unit. The input switch unit includes a plurality of switches configured to con-nect and disconnect one of the first and second input nodes and one of the first capacitor and the second capacitor. The input switch unit further includes a first charge pump coupled to the first input node and a second charge pump coupled to the second input node. The first charge pump is configured to generate, based on a clock signal, switching signals for a switch of the plurality of switches, and the second charge pump is configured to generate, based on the clock signal, switching signals for a further switch of the plurality of switches.
