Abstract
The present disclosure describes a digital-to-analog converter (DAC) comprising a programmable integrated circuit, a resampler, and a clock. The programmable integrated circuit may be configured to perform delta-sigma modulation to convert a digital signal to a coarse representation of an analog signal. The coarse representation of the analog signal may be sent to a first-stage of the resampler. After processing the signal, the first-stage of the resampler may pass a continuous signal to the second-stage of the resampler. The second-stage of the resampler produce a clean sampling instant for the signal that represents the point in time where the signal transitions from discrete time to continuous time. The analog signal may then be outputted to one or more receivers.
