Techniques for canceling offsets in differential circuits
A circuit includes a differential circuit that generates a differential output signal at first and second output nodes. The circuit also includes a first variable capacitor coupled to the first output node of the differential circuit, and a second variable capacitor coupled to the second output node of the differential circuit. A control circuit controls capacitances of the first and the second variable capacitors in response to a measurement of the differential output signal.
