Abstract
Embodiments provide a data receiving circuit. The data receiving circuit includes a first amplifier circuit and a second amplifier circuit. The first amplifier circuit is configured to receive a data signal, a first reference signal and a second reference signal, perform a first comparison between the data signal and the first reference signal and output a first signal pair, and perform a second comparison between the data signal and the second reference signal and output a second signal pair. The second amplifier circuit is configured to select to receive the first signal pair or the second signal pair as input signal pairs based on a feedback signal, amplify a voltage difference between the input signal pairs, and output a first output signal and a second output signal, wherein the feedback signal is obtained based on previously received data.
