ABSTRACT:
An analog to digital converter may include an input switch array configured to alternately sample a first and a second input signal to a first and a second input capacitor during two different sample time intervals, an integrator having a first and second integration capacitor, and a cross switch array coupled to the input switch array and the integrator. The cross switch array may be configured to alternately transfer charges from the first and second input capacitors to the first and second integration capacitors during two different transfer time intervals. A system including an analog to digital converter consistent with an embodiment and an associated method of sampling and transferring charges in an analog to digital converter are also provided.
