摘要: An apparatus includes a delay line having at least two parallel branches, where each branch multiple cells coupled in series. The is configured to receive an input signal and propagate the through branches. also sampling circuits sample different taps branches of output sampled values. first are associated with amounts compared second At some could have minimum delay, difference between one tap be less than smallest delays.
