Abstract :
This comment points out an error in a well accepted fundamental signal-to-noise ratio (SNR) equation for asynchronous ADCs, and presents a correct SNR equation. Meanwhile, a wrong concept of calculating mean-related quantities for non-uniform sampling analysis is corrected. The result is validated by MATLAB simulation.
