Abstract:
A decision feedback equalization (DFE) technique suitable for high data-rate I/O link receivers is presented. The technique leverages quarter-rate data slicing to implement a fully speculative 3-tap DFE and uses clock forwarding to reach a speed of 50Gb/s. It corresponds to 20ps timing closure of the most critical path, which is the feedback of the first DFE tap. The RX data-path is implemented in 14nm FinFET CMOS SOI technology. At 0.9V supply the energy-efficiency is 1.6pJ/b when PRBS15 data transmitted at 50Gb/s across a channel with 32.5dB insertion loss are recovered with >30% horizontal margin (BER<;10-12).
