A 40gb/S Low Power Transmitter With 2-Tap Ffe And 40:1 Mux In 28nm Cmos Technology

This paper introduces a low power NRZ transmitter with 2-tap multiple-FFE operating at 40Gb/s. The transmitter incorporates 3-stage MUX, a tailless CML driver and a resistance calibration system. Simplifying low speed MUX, modifying high speed MUX structure and adopting tailless CIVIL save a lot of power and improve signal quality. The simulation results show that the design can work at 40Gb/s with a -14.8 dB RLGC channel in 28nm CMOS technology. The simulation power consumption is 16.83 mW under 1.05V supply.
