Abstract
A switching component comprises a plurality of switches configured to receive a differential signal at an input and is configured to provide a non-inverted version of the differential signal at an output during a first phase of operation and an inverted version of the differential signal at an output during a second phase of operation. A driver amplifier component is configured to receive the non-inverted version of the differential signal at an input during the first phase of operation and the inverted version of the differential signal at an input during the second phase of operation. A sampling capacitor component is configured to sample the output of the driver amplifier component during the first phase of operation and the second phase of operation.
