A mixed-signal decision-feedback equalizer that uses parallelism

A mixed-signal decision-feedback equalizer (DFE) that uses parallelism is described. The parallelism in the look-ahead DFE achieves an increase in the data rate over that of a conventional DFE. The DFE occupies 23 mm/sup 2/ in a 2-/spl mu/m CMOS process, operates at 55 Mb/s and dissipates 450 mW.
