An Energy-Efficient 3Gb/s PAM4 Full-Duplex Transmitter With 2-Tap Feed Forward Equalizer

Abstract: We present a full-duplex 3 Gb/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 65 nm Digital CMOS process, the transmitter transmits a maximum of 1 V peak-to-peak differential output swing. In full-duplex mode, the transmitter equalizes 2 m UTP cable and dissipates 37.3 mW at 3Gb/s with echo canceller in the receiver path. The power reduces to 18.3 mW while transmitting across a 9 m UTP cable in the half-duplex mode.

Wireline communication: the backbone of data transfer

Abstract: This paper reviews the need of a high performance wireline communication in the background of wirelessly connected billions of sensor nodes by 2020s. It compares the performance of the state-of-the-art wireline transceivers and underlines the challenges in improving the performance in the midst of tapering in CMOS technology scaling. This paper elaborates on the ongoing research to track the increasing bandwidth requirements in processing platforms with an affordable power budget. Energy efficient design techniques for clock recovery in multilane receivers, receiver frontend in digital CDRs, reconfigurable voltage-mode transmitter, and PAM4 equalizer in full-duplex transceivers are discussed.
