Abstract
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%.
