Multi-bit fractional equalization for multi-Gb/s inductively coupled connectors

Multi-bit fractional equalization at the driver side allows for multi-Gb/s signaling across transformers which suffer from excessive ISI in inductively coupled connectors and backplanes. When an inductively coupled element is place in a transmission line or the gap between inductors in a transformer increases, the amplitude of the coupled pulse is decreased while the natural decay of the pulse is maintained. By removing the effects of the natural decaying tail of the pulse created by coupling an NRZ signal across a transformer, high-speed inductive coupling can be achieved over the larger transformers required by connectors and backplanes.
