Abstract

One embodiment of the present disclosure relates to a circuit. The circuit includes a digital to analog converter (DAC) configured to convert a time-varying, multi-bit digital value to a corresponding time-varying output current. The circuit also includes a mixer module downstream of the DAC and comprising a plurality of mixers. A control block is configured to selectively steer output current from the DAC to different mixers of the mixer module. Other techniques are also described.
