A 200Mb/s-2Gb/s Oversampling RX with Digitally Self-Adapting Equalizer in 0.18/spl mu/m CMOS Technology

Abstract

This paper presents a 6x OSR receiver for 200M-2Gb/s, comprising an adaptive equalizer that is auto-calibrating on sample data statistics. This robust and highly digitized receiver is demonstrated in 0.18mum CMOS and can equalize variable cable losses up to 22dB. The self-adaptive equalizer solution occupies only 0.08mm2 and consumes 9-16mW
