Abstract
One example described herein relates to a digital to analog converter (DAC). The DAC includes a digital signal input configured to receive a multi-bit digital input signal, and a plurality of unit cells arranged in rows and columns. A row decoder and a column decoder provide respective control signals to respective rows and respective columns to selectively couple a number of the unit cells to an output of the DAC. The number of unit cells which are coupled to the output by the control signals is dependent on the multi-bit digital input signal. At least one of the control signals is modulated based on a local oscillator signal.
