ABSTRACT:
A digital/analog converter comprising a coarse bit decoder for decoding M higher-order bits of an (M+N)-bit input digital signal, a fine bit decoder for decoding N lower-order bits of the (M+N)-bit input digital signal, a current scaler for classifying currents into a plurality of steps and outputting a selected one of the classified step currents in response to an output signal from the coarse bit decoder, a current/voltage converter for converting an output current from the current scaler into a voltage, a voltage elevator for outputting an output voltage from the current/voltage converter as a reference voltage, a voltage divider for dividing the reference voltage from the voltage elevator into a plurality of steps and outputting a selected one of the divided step voltages in response to a switching control signal from the fine bit decoder, and a current compensator for compensating for an amount of current flowing through the voltage divider to make the reference voltage in the voltage divider constant in level.
