Abstract
A 4-level pulse amplitude modulation (PAM-4) decoder including: a comparator configured to receive first input data, second input data, and a clock signal and output first comparison data and second comparison data, wherein the first comparison data and the second comparison data are comparison results for the first input data and the second input data; a clock delay circuit configured to delay the clock signal and generate a delayed clock signal; and a time-windowed least significant bit (LSB) decoder configured to receive the first comparison data, the second comparison data, and the delayed clock signal, wherein the time-windowed LSB decoder is configured to perform a decoding when the delayed clock signal is at a first level.
