Abstract:

A 2 $times$ 56 Gb/s 0.78-pJ/b four pulse-amplitude modulation (PAM-4) single-ended multiple-input multiple-output (MIMO) crosstalk cancellation and signal reutilization (XTCR) receiver (RX) is investigated for medium-reach (MR) backplane communications. An XTCR scheme based on active crosstalk extraction (A-XTCR) is proposed to improve the signal reutilization efficiency of the RX. By …
