Abstract
A digital-to-analog converter (DAC) includes a current array having a plurality of unit cells in a plurality of rows and a plurality of columns, an arbitrary switch box and processing circuitry configured to randomly select a subset of rows among the plurality of rows based on a plurality of first row selection signals, the subset of rows including first unit cells among the plurality of unit cells, randomly select one row among the plurality of rows based on a plurality of second row selection signals, select a subset of columns among the plurality of columns based on column selection signals, second unit cells among the plurality of unit cells being included in both the one row and the subset of columns, and generate an analog output signal corresponding to a digital input signal based on the first unit cells and the second unit cells.
