Abstract

This paper demonstrates an active near-end crosstalk (NEXT) noise canceller intended for use in commercial backplanes. Optimum system architecture and specifications are generated using measured channel data. Additionally, CMOS circuit implementation approaches are introduced and their performances are discussed. The NEXT canceller is applied to a 20Gbps 4-PAM signal over a 16-inch backplane channel and shows 75% cancellation.
