This paper describes a 1-tap DFE with unfixed tap coefficient. According to the data patterns, the inter-symbol interference (ISI) is changed. The data patterns will be predicted using the DC level detector and the tap coefficient of the DFE will be adjusted to achieve high gain against high attenuation. The proposed 1-tap DFE with unfixed tap coefficient solves a high channel loss problem while it consumes low power. Designed in 65-nm CMOS technology, a 20 Gb/s receiver is composed of 1-tap half rate DFE with unfixed tap coefficient which compensates 20 dB attenuation, and it consumes 22.65 mW for 1-V supply.
