Abstract:
1. A data receiver of a semiconductor integrated circuit, the data receiver comprising: a plurality of receiver units, each of the plurality of receiver units including: a plurality of level detectors, each of the plurality of level detectors configured to detect different signal levels and receive data according to a clock signal having a predetermined phase difference and perform an amplification operation including an equalization function based on feedback data, thereby outputting an amplification signal; and an encoder configured to receive the output signals of the plurality of level detectors, wherein level detectors of one receiver unit are configured to receive an amplification signal, as the feedback data, from level detectors of another receiver unit that receives a first clock signal having a phase more advanced than a phase of a second clock signal received in the one receiver unit, wherein the plurality of level detectors include: wherein the high-level detector includes:
