This ebook introduces readers to the layout of adaptive equalization suggestions built-in in ordinary CMOS know-how for high-speed serial hyperlinks. on the grounds that continuous-time equalizers provide a number of benefits as a substitute to discrete-time equalizers at multi-gigabit charges, this e-book offers an in depth description of continuous-time adaptive equalizers layout - either at transistor and method levels-, their major features and performances. The authors commence with a whole overview and research of the state-of-the-art of equalizers for wireline purposes, describing why they're important, their forms, and their major purposes. subsequent, theoretical basics of continuous-time adaptive equalizers are explored. Then, new buildings are proposed to enforce the various construction blocks of the adaptive equalizer: line equalizer, loop-filters, energy comparator, and so on. The authors display the layout of a whole low-power, low-voltage, high-speed, continuous-time adaptive equalizer. eventually, an economical CMOS receiver together with the proposed continuous-time adaptive equalizer is designed for 1.25 Gb/s optical communications via 50-m size, 1-mm diameter plastic optical fiber (POF).

Nowadays, the extreme simplicity of POF has come at the expense of lower transmission capacity with respect to GOF. The main drawback of SI-POF is the bandwidth-length product of approximately 45 MHz · 100 m due to mainly strong chromatic and mode dispersion [ZIE08]. This small BW, quite unsuitable for gigabit communications, limits the maximum non-return-to-zero (NRZ) data rate that can be properly transmitted through SI-POF, since, when the data rate is much higher than the BW of the channel, ISI appears and affects the BER of the whole communication system.
