Abstract :
This paper presents an adaptive equalizer circuit using filter switching for 5 Gb/s data communication over electrical backplane. Most of conventional equalizers are based on amplification of high frequency component of the received signal, and the performance degrades when the line is very short and the attenuation is small. The proposed one solves this issue by using two signal paths, high-pass and low-pass path, and switching them based on the received signal. It can compensate 5 Gb/s PRBS through FR4 backplane in 0 cm, 25 cm, 50 cm and 75 cm long both with and without pre-emphasis.
