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