This paper presents a 2.5–8Gb/s transceiver for PCI Express Gen3.0/2.0/1.0 applications. To overcome channel loss of high bit rate application, a linear equalizer (LEQ) and decision feedback equalizer (DFE) are used to eliminate ISI effect, compensate channel loss, and improve BER performance for 28-inch FR4 channel. The 3-tap feed-forward equalizer(More)
