FOLDING A/D CONVERTER

摘要

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.
