摘要：An A/D converter having capacitors of a first array of sampling capacitors

weighted in binary code connected between a first common circuit node and an inputterminal to be charged to an input voltage with respect to a ground of a signal to beconverted, and in accordance with SAR technique are then selectively connected with twodifferential reference terminals, and at the same time capacitors of a second array equalto the first and all connected to a second node are selectively connected to ground andthe lower differential voltage terminal. The two nodes are connected to the respectiveinputs of a comparator. A logic unit controls the connections of the capacitors of the twoarrays in accordance with a predetermined timing program and as a function of theoutput of the comparators.
