Abstract
A digital-to-analog converter adapted for use as a feedback converter in a continuous time sigma delta analog-to-digital converter. The digital-to-analog converter has a discrete time digital signal input accepting digital signal samples that are synchronized with an assertion of a first data clock signal and a discrete time clock generator that generates an output pulse in response to receiving an assertion of the first data clock. The output pulse is asserted for a fixed duration that is independent of a jitter of the first data clock. The digital-to-analog converter also includes a continuous time analog output that produces, during assertion of the output pulse, a continuous time analog output signal having a magnitude corresponding to the digital signal samples.
