Abstract:
A digital-to-analog converter having a structure that converter may decrease an effect of a mismatch between elements and decrease a quantity of the elements. The digital-to-analog converter includes a multiplexer configured to output a first voltage or a second voltage corresponding to an input bit as an input voltage and a recursive switched circuit configured to alternately receive the input voltage and a reference voltage and to output an average value of the input voltage and the reference voltage as an output voltage.
