Abstract :
A mixed-signal RAM decision-feedback equalizer (DFE) that operates at 90 Mb/s is described. The DFE cancels intersymbol interference caused by the past 4 decisions. The RAM contents are adapted using digital circuits. In steady-state operation, power dissipation is 260 mW. The active area is 4.5 mm/sup 2/ in a 1-/spl mu/m CMOS process.
