Abstract: A dichotomizing, high speed analog - digital comprises an input stage for the voltage - current conversion of the analog signal, a reference current source, a sequence of N-1 identical cells in series, each comprising a comparator and current dividers, a terminal cell incorporating a comparator, a digital coder receiving a digital signal from each cell and, optionally, a link positioned between the consecutive cells. The analog signal is processed in the cells entirely in current form, the link means making it possible to isolate the potentials between successive cells.
