The performance of recent high-speed VLSI systems is significantly lim-ited by the interconnection bandwidth inside/between chips relative to individual transistor performance. However, the attenuation or deterio-ration 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 includ-ing inductive-coupling wireless communication to compensate for the frequency-dependent loss of wiring, resulting in improving a data transfer rate.
