Abstract :
A 35 Mb/s mixed-signal adaptive decision-feedback equalizer (DFE) has been implemented in a 2-μm CMOS technology. The DFE has four feedback taps for cancelling intersymbol interference (ISI) and one tap for cancelling dc offset. The ISI is cancelled using fully differential analog circuits. Coefficient adaptation is digital, and two adaptation rates are available. The DFE occupies 24 mm2 and dissipates 165 mW
