Echo-Free and Crosstalk-Free Transmission in Particular Interconnections

We explore several designs for implementing the special ZXtalk method for completely degenerate interconnections, capable of providing reduced echo and internal crosstalk in multiconductor interconnections. Transmission circuits comprising a MIMO series-series feedback amplifier are adequate to obtain a wide bandwidth. The external crosstalk may also be reduced, using an additional conductor to obtain a pseudo-differential scheme.
