Equalization Techniques for Multiple-Valued Data Transmission and Their Application
Yasushi Yuminaka and Kazuyoshi Yamamura
The performance of recent high-speed VLSI systems is significantly limited by the interconnection bandwidth inside/between chips relative to individual transistor performance. However, the attenuation or deterioration of signals, arises from physical phenomena in transmission lines, restricts the maximum frequency at which the signal can transmit. This paper investigates data recovery techniques especially for multiple-valued data transmission in order to achieve high-speed data transmission in VLSI systems. We discuss various types of equalization techniques including inductive-coupling wireless communication to compensate for the frequency-dependent loss of wiring, resulting in improving a data transfer rate.
