Abstract
A system for reducing near-end crosstalk (NEXT) includes a first electrical component contributing to a first NEXT pulse of a first polarity and a second electrical component receiving the first NEXT pulse at a first time delay (td). A circuit couples the first electrical component to the second electrical component to create a second NEXT pulse of a second polarity and delays the second NEXT pulse by an amount equal to the first time delay (td). The first and second NEXT pulses are combined to reduce the first NEXT pulse. A method for reducing NEXT includes coupling a first component contributing to a first NEXT pulse of a first polarity and a second component to create a second NEXT pulse of a second polarity, delaying the second NEXT pulse, and combining the second NEXT pulse with the first NEXT pulse to reduce the first NEXT pulse.
