In this letter, an adaptive equalizer with an inter-symbol interference (ISI) level measurement using a periodic training pattern is presented. The compensation level of the equalizer is determined by measuring ISI level and fed back to the feed-forward equalizer. The proposed algorithm is verified with a 100-cm flexible flat cable (FFC) at 10 Gb/s data rate using a 90 nm CMOS process technology. Compensation range is from 15 dB to 33 dB with a tuning range of 18 dB, and the current consumption is 7.6 mA at 1 V power supply.
