Abstract
A decision-feedback equalizer (DFE) includes a combining circuit and a feedback filter. The combining circuit combines an input signal and at least one feedback signal to generate an equalized signal. The feedback filter generates the at least one feedback signal according to the equalized signal, and includes a controllable delay circuit. The controllable delay circuit receives an output signal that is derived from the equalized signal, and applies at least one delay amount to generate at least one delay signal, wherein the at least one feedback signal is derived from the at least one delay signal.
