Abstract: Transient response generating circuit A has a first circuit 3 that generates transient response OUT1 in a first polarity direction, a second circuit 4 that generates transient response OUT2 in a second polarity direction opposite to the first polarity, and a transient response synthesizing circuit 6 that combines the transient response OUT1 in the first polarity direction and the transient response OUT2 in the second polarity direction to generate composite transient response OUTC.
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 (INO) 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.
