ABSTRACT:
The invention provides a method and system for reducing capacitive coupling for transmission lines. Where there is a plurality of parallel transmission lines, a first half of the transmission lines (every second one) are inverted at their driving points, and are reinverted at a half-way point between their driving points and their receiving points, using an inverter placed halfway along the transmission line. A second half of the transmission lines are inverted at the half-way point, and are reinverted at their receiving points. Thereby, every second one of multiple transmission lines is inverted at any point in the transmission line, causing capacitive coupling to self-cancel across the entire transmission line, reducing crosstalk and speeding rise time.
