We present a full-duplex 3Gb/s PAM4 voltage-mode transmitter with an embedded 2-tap feed forward equalizer. In full-duplex mode, the transmitter employs an echo canceller to cancel the locally transmitted signal and recover the signal from the far-end. The transmitter achieves energy proportionality with output swings and equalizer coefficients. Fabricated in 65nm Digital CMOS process, the transmitter transmits a maximum of 1V peak-to-peak differential output swing. In full-duplex mode, the transmitter equalizes 2m UTP cable and dissipates 37.3mW at 3Gb/s with echo canceller in the receiver path. The power reduces to 18.3mW while transmitting across a 9m UTP cable in the half-duplex mode.
