Abstract

PURPOSE: To simplify IC implementation with the number of comparator circuits reduced, by applying the voltage obtained by sample-holding an input analog signal to an analog comparator circuit in parallel and by extracting the companding PCM code, which corresponds to the input analog, while reference voltages are changed over by a logic circuit.
