Digital-to-analog converter circuit and electronic device including same and method for controlling same

Abstract

A digital-to-analog converter (DAC) circuit is provided. The DAC circuit includes: a serializer circuit including a plurality of multiplexers and configured to convert a parallel code in digital form into a serial code using the plurality of multiplexers; and a cell array including a plurality of unit cells and configured to output an analog signal based on the serial code. The serializer circuit includes: a pseudo random number generation circuit configured to generate random numbers in response to edges of a first clock signal; a first switch circuit connected to a first multiplexer; a second switch circuit connected to a second multiplexer; and a random number circuit configured to transmit different random numbers generated by the pseudo random number generation circuit in response to different edges of the first clock signal to the first switch circuit and the second switch circuit, respectively.
