4×12 Gb/s 0.96 pJ/b/lane analog-IIR crosstalk cancellation and signal reutilization receiver for single-ended I/Os in 65 nm CMOS

Abstract

A crosstalk cancellation and signal reutilization (XTCR) algorithm implemented with analog-IIR networks dramatically improves signal integrity across 4 closely-spaced single-ended PCB traces. The prototype XTCR design implemented in 65 nm CMOS improves the measured average horizontal and vertical-eye openings of the 4 channels by 37.5% and 26.4% at 10-8 BER, while consuming only 0.96 pJ/b/lane.
