Abstract
Certain aspects of the present disclosure generally relate to circuitry and techniques for digital-to-analog conversion. One example device for digital-to-analog conversion generally includes: a digital-to-analog converter (DAC) having an input coupled to an input node of the device; a first return-to-zero (RZ) DAC having an input coupled to an input node of the device; and a combiner, wherein an output of the first DAC is coupled to a first input of the combiner, and wherein an output of the first RZ DAC is coupled to a second input of the combiner.
