Abstract
An analog adaptive decision-feedback equalizer (DFE) is described. The DFE
cancels intersymbol interference using four feedback taps, and a fifth tap
cancels de offset. The coefficient for each tap is adapted using a small mi
xed-signal integrator. The DFE dissipates 220 mW at a data rate of 150 Mb/s
. The active area is 1.8 mm(2) in a 1-mu m CMOS process.
