Low power Fast Ethernet equalizer

A low power adaptive analog cable equalizer has been designed in 0.18 μm CMOS technology for 100 Mb/s Fast Ethernet. The equalizer can compensate skin losses of cables with lengths up to 100 m. Furthermore it also incorporates compensation of flat loss and DC-shifts. Hence this equalizer performs compensation of all relevant Fast Ethernet signaling issues. The circuit consumes only 10.1 mW from 1.8 V supply, which to the best of our knowledge is the lowest power consumption reported to date.
