Decision feedback equalizer and method for performing decision feedback equalization on input signal in decision feedback equalizer

Abstract

A decision feedback equalizer (DFE) and a method for performing decision feedback equalization on an input signal in the DFE are provided. The DFE includes a first comparator, a first calculating circuit, a second comparator and a second calculating circuit. The first comparator is configured to compare a first calculation signal with a first threshold to generate a first comparison result, and the first calculating circuit is configured to generate the first calculation signal according to the input signal and a first delayed signal of the first comparison result. The second comparator is configured to compare a second calculation signal with a second threshold to generate a second comparison result, and the second calculating circuit is configured to generate the second calculation signal according to the input signal and a second delayed signal of the second comparison result.
