  • Patent number: 11671236
    Abstract: The present invention provides a receiver including a sampling circuit, a data sampling point selection circuit and a determination circuit. The sampling circuit is configured to use a clock signal to sample an input signal to generate a sampled signal, wherein a frequency of the clock signal is greater than a frequency of the input signal. The data sampling point selection circuit is configured to filter start point data to generate a filtered start point data, and to generate a data sampling point by adding an offset to the filtered start point data, wherein the start point data corresponds to a time point that a sampled value of sampled signal starts to change. The determination circuit is configured to refer to a sampled value corresponding to the data sampling point in the sampled signal to determine a logical value of a digital output signal corresponding to the input signal.
