Abstract
The embodiments described herein provide a digital-to-analog converter (DAC). The DAC implements a stepped return-to-zero (RZ) pulse scheme, where the DAC output includes the superposition of multiple time-offset RZ pulses. In one embodiment, the DAC includes a first switching element, a second switching element, a current source, and a current sink. The first switching element generates first RZ pulses, and the second switching element generates second RZ pulses, where the second RZ pulses are time-offset from the first RZ pulses. The first RZ pulses and second RZ pulses are combined to provide stepped RZ pulse output signal.
