Abstract
A receiver circuit includes a source-follower input stage and a far-end crosstalk (FEXT) reduction circuit. The source-follower input stage is configured to receive a first signal over a first transmission line. The FEXT reduction circuit is coupled to the source-follower input stage and is configured to derive, from a second signal on a second transmission line, an approximated FEXT signal that approximates an interfering signal induced in the first transmission line by the second signal, and reduce a level of the interfering signal by combining the approximated FEXT signal and the first signal.
