Abstract
In a folding A/D converter, a comparison part CPM provides a plurality of comparison signals Sc1 . . . Sc9 in response to an input signal Si. The transients in the comparison signals Sc1 . . . Sc9 are mutually shifted and substantially overlap. Because of the overlap, only a relatively small input signal variation is needed to pass all the transients. A limiting part LIM effectively selects portions of the transients. A combining part CBM effectively multiplexes these selected portions into a folding signal Sf. The selection by the limiting part LIM prevents distortion of the folding signal Sf, despite the overlap.
