摘要

采用双二进制PAM4编码技术设计了112Gb/s的SerDes发射机，有效地解决了串行收发器在强信道时间下的高误码率问题。采用双二进制PAM4编码技术，解决了高速PAM4 (Pulse Amplitude Modulation-4)信号在强信道下过度衰落的问题。发射器由CMOS 28nm工艺供电，电压为0.9V。仿真结果表明，该发射机工作速度为112Gb/s，信道衰减为20.9dB，电源电压为0.9V，直流功耗为212.8mW，能效为1.9pJ/bit，灵敏度为88.3%。

112Gbps High-speed SerDes Transmitter Based on Duo-Binary Pam4 Encoding

A 112Gb/s SerDes transmitter has been designed using Duo-binary PAM4 coding technology to effectively deal with the problem of high BER in serial transceivers under strong channel time. Using Duo-binary PAM4 coding technology, the problem of excessive fading of high speed PAM4 (Pulse Amplitude Modulation-4) signals under strong channels has been solved. The transmitter is powered by a CMOS 28nm process at 0.9V. Simulation results show that the transmitter can operate at 112Gb/s with 20.9dB channel attenuation, a supply voltage of 0.9V, a DC power consumption of 212.8mW, an energy efficiency of 1.9pJ/bit, and a sexiness of 88.3%.
