ABSTRACT:
A sub-ranging analog-to-digital converter includes, in cascade, a coarse converter, a digital-to-analog converter, a subtracter circuit and a fine converter. Errors of the coarse converter are detected in the fine converter by means of an overflow detector and an underflow detector which generate an overflow signal (OF) and an underflow signal (UF), respectively. The digital output (D.sub.A) of the coarse converter is corrected by first subtracting one LBS in a decoder and then, in response to the overflow and underflow signal, adding thereto zero, one or two LBSs.
