  • Data receiver and data receiving method
    Patent number: 7741880
    Abstract: A data receiver and a data receiving method in which the data receiver generates two comparison signals based on amplitude modulated differential input signals, amplifies the comparison signals, compares amplified signals, and outputs logic operation results based on the amplitude modulated differential input signals and the comparison signals, thereby detecting data bits. Accordingly, the number of necessary amplifiers and comparators is reduced and a separate reference voltage generator is not needed, so that chip size reduction and low-power operation is accomplished.
    Type: Grant
    Filed: February 22, 2007
    Date of Patent: June 22, 2010
    Assignees: Samsung Electronics Co., Ltd., Korea Advanced Institute of Science and Technology
    Inventors: Young-su Cha, Kyoung-Hoon Yang
