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.

Abstract: A sensing apparatus that senses electrical signals of a plurality of pixels arranged in rows or columns. The sensing apparatus includes a plurality of sensing circuits configured to sense electrical signals through sensing lines that correspond to the columns of the pixels, a first switch configured to connect a first sensing line of the sensing lines that corresponds to a first pixel column of the columns of the pixels and a first sensing circuit of the sensing circuits that corresponds to the first pixel column; and a second switch configured to connect the first sensing line and a second sensing circuit of the sensing circuits different from the first sensing circuit.
