Abstract
A controlled sampling module samples an input signal from an input device and a reference signal. The controlled sampling module includes a plurality of sample capacitors, a switching network, and a switch control module for controlling the switching network. The switching network couples a first capacitor of the plurality of capacitors to the reference signal during a first phase, and to the input signal during a second phase, such that a charge on the first capacitor remaining at an end of the first phase is cancelled during the second phase.
