Abstract

Disclosed is a decision feedback equalizer, which includes a summator that receives a gray code-based PAM-4 signal, a first bit signal, and a second bit signal, and outputs an input voltage obtained by adding a preset coefficient to a voltage level of the PAM-4 signal in response to the first bit signal and the second bit signal, and a decoder that receives the input voltage and first to third reference voltages of the PAM-4 signal and outputs the first bit signal and the second bit signal, and the decoder includes a first comparator that outputs the first bit signal by comparing a magnitude of the input voltage with a magnitude of the first reference voltage, and a second comparator that outputs the second bit signal by comparing charge-discharge intensities of the input voltage and the second and third reference voltages.
