Abstract

See full text

An apparatus and method for digital-to-analog conversion. A digital-to-analog converter includes a sampler for resampling a digital signal and a DAC array. The DAC array includes a sequencer, a unit element activator, and an array of one-bit DACs (unit elements). The unit elements are activated in a cyclical sequence, based on the resampled digital signal. Unit elements in the sequence may be skipped, based on a disruption probability. The disruption probability may be determined randomly, or pseudo-randomly. Output signals of the unit elements are summed or averaged to form an analog signal. The converter may include a filter to filter the analog signal.
