摘要：

This brief presents the theoretical and simulation results of the effects of flying-adder (FA) clocks on digital-to-analog converters (DACs). A closed-form expression for the frequency spectrum of the DAC output is derived. Analyses show that there exists a lower bound of the clock frequency above which the FA clock does not introduce any additional frequency components in the DAC output. For an FA clock of frequency between the Nyquist frequency and this lower bound, a closed-form expression of the DAC signal-to-distortion ratio is derived.
