  • System and Method for a Switched Capacitor Circuit
    Publication number: 20130335131
    Abstract: In an embodiment, a circuit includes a forward path circuit having an auto-zero switch coupled between an input of an amplifier and an output of the amplifier, a first chopping circuit having an input coupled to an input of the forward path circuit and an output coupled to the input of the amplifier, and a second chopping circuit having an input coupled to the output of the amplifier and an output coupled to an output of the forward path circuit. The circuit further includes a feedback circuit that has a feedback switch, a feedback capacitor including a first end coupled to an output of the amplifier, a third chopping circuit coupled between the input of the forward path circuit and a first end of a feedback switch, and a fourth chopping circuit coupled between a second end of the feedback switch and a second end of the feedback capacitor.
