In accordance with an embodiment, a circuit includes an analog chopping circuit having a first input coupled to a system input and a second input coupled to a first chopping signal, an oversampled data converter having an input coupled to an output of the analog chopping circuit, where the oversampled data converter is configured to produce an oversampled digital signal at an output of the oversampled data converter. The circuit further includes a digital filter having an input coupled to the output of the oversampled data converter, and a digital chopping circuit including a first input coupled to the output of the oversampled data converter, and a second input coupled to a second chopping signal. The digital filter is configured to filter quantization noise generated by the oversampled data converter.
