PROJECT TITLE :
Equalization for Electrical Links: Current Design Techniques and Future Directions
Another article in this issue, the introductory article by Tony Chan Carusone, mentioned how the limited bandwidth of an electrical channel causes distortion (e.g., broadening) of the pulses traveling from transmitter to receiver. While not compensating for such distortion, the utmost data rate of a typical electrical link would be restricted to only some gigabits per second to avoid excessive intersymbol interference (ISI). The key to achieving dramatically higher information rates (up to fifty six Gb/s in the newest proposed standards) is to employ channel equalization. This article describes the most common sorts of equalizers utilized in electrical links today.
