Abstract
The power consumption of wireline circuits has
become increasingly more critical as the pin count and data rate
rise. This paper describes a power scaling methodology and a new
half-rate speculative architectur e for decision-feedback equalizers
(DFEs) to relax the speed-power trade-offs. Designed in 90-nm
CMOS technology, a 20-Gb/s prototype consisting of a linear
equalizer and a one-tap DFE compensates for the loss of an 18-in
FR4 trace while drawing 40 mW from a 1-V supply.
