Multi-tap decision-feedback-equalization (DFE) is proposed to counteract inter-symbol interference (ISI) in high-speed backplane data communications. A MATLAB program has been developed to optimize the DFE tap coefficients for a given backplane channel. A multi-tap DFE receiver with an optional analog pre-equalizer implemented in 0.18µm CMOS technology demonstrates 8Gb/s operation with PRBS15 data over a 34" FR4 backplane. 0-7803-9195-0/05/$20.00 ©2005 IEEE.
