Patent abstract
A digital encoder having a dynamic element matching (DEM) processor is divided into a master DEM circuit and N slave DEM circuits. The master DEM circuit encodes a multibit digital input signal (IN0) into parallel codes (C1) corresponding to the coefficient of a plurality of output nodes on the basis of a prescribed DEM algorithm. Each of the N slave DEM means (2) has 3 or more output nodes. Code (C1) from the master DEM circuit is encoded into parallel codes (C2) with the same weighting for each code and corresponding to the configuration of the 3 or more output nodes on the basis of a prescribed DEM algorithm, and the obtained parallel codes are output in parallel from 3 or more output nodes.
