Abstract: A decision feedback equalizer including: a first input latch configured to generate a first output signal from first data received by the first input latch, wherein the first input latch includes: a first sub-circuit configured to receive the first data and a reference voltage, compare the first data and the reference voltage, and generate first internal signals having different transition timings according to a result of the comparison between the first data and the reference voltage; and a second sub-circuit configured to receive, as first feedback, a second output signal, which corresponds to second data received by the first latch earlier than the first data, and generate the first output signal, which compensates for a difference between the transition timings of the first internal signals, based on the first feedback.

Abstract: An electronic device includes processing circuitry outputting first to third signals, delaying first to third signals to output fourth to sixth signals, generating a pulse signal based on the fourth signal, the fifth signal, and the sixth signal, detecting lengths of intervals, and adjusting at least one of a first code, a second code, and a third code based on fourth codes.
