ABSTRACT:
A digital-to-analog converter of current segment type, having a plurality of first variable current sources and a second variable current source of the same structure as the first variable current sources. The converter further comprises a comparator. The comparator compares a voltage corresponding to the output current of the second variable current source with a reference voltage. The difference between these compared voltages is used to determine the output currents of the first variable current sources.
