Abstract
An apparatus includes a plurality of binary weighted capacitors coupled between a first input terminal of a comparator and a plurality of signal buses, wherein the plurality of binary weighted capacitors has a binary weight increasing by two times from a first capacitor to an (N−K)th capacitor, and a constant binary weight from the (N−K)th capacitor to a (N−K−2+2)th capacitor, an offset voltage generator configured to generate a digitally controlled offset voltage having 2steps fed into a second input terminal of the comparator, and a successive approximation logic block configured to receive an output signal of the comparator, and generate an N-bit control signal for controlling the plurality of binary weighted capacitors.
