A CMOS DFE (decision feedback equalization) receiver with a negligible overhead in chip area and power consumption was implemented by cross-coupling the outputs of a conventional 2-way interleaving receiver to the other side of the input. Application of this receiver to the SSTL interface channel showed the increase of sampling time window by 60 /spl sim/120% at data rates from 800 Mbps up to 1.2 Gbps. Chip area and power consumption are 80/spl times/100 /spl mu/m and 2.5 mW respectively with a 0.25 /spl mu/m 1-poly 5-metal CMOS process at the supply voltage of 2.5 V.
