Claim 0:
1. A filter for an analog-to-digital converter, the filter comprising:
a first integrator having a first integrator clock input, a data input, and a data output;
a first differentiator having a first differentiator clock input, a data input, and a data output;
a first switch coupled between a data output of the first integrator and a data input of the first differentiator, the first switch having a first switch input;
a second differentiator having a second differentiator clock input;
a second switch coupled between the data output of the first integrator and a data input of the second differentiator, the second switch having a second switch input; and
a clock circuit coupled to the first integrator clock input, the first and second differentiator clock inputs, and to the first and second switch inputs, the clock circuit comprising:
a first clock generator coupled to the first integrator;
a second clock generator coupled to the first switch and to the first differentiator; and
a third clock generator coupled to the second switch and to the second differentiator.
