An interleaved DAC utilizes a set of positive sub-DACs and a set of negative sub-DACs for converting digital inputs in parallel without return to zero. For each digital input, a positive sub-DAC performs conversion and drives its analog output for a duration of N/f; and a negative sub-DAC performs conversion and drives its analog output for a duration of (N&#x2212;1)/f; and by a delay of 1/f. By combining the outputs from the two sets of sub-DACs, the output from the positive sub-DAC is effectively removed when it is no longer needed at the combined output. As a result, the combined analog signal has each data point valid only for a duration of T, thereby achieving the desired data conversion speed of f.
