Abstract
A data signal may be sampled at high speed using a clock signal by propagating the data signal and the clock signal through a series of data and clock delay elements, respectively, and latching the corresponding delayed data and clock signals. The sampling speed is thereby controlled by the relative skew between the clock and data signals, which can be made relatively small and may be limited only by noise and random variations in fabrication. Accordingly, high speed sampling may be obtained.
