A 200GS/s 8b 20fJ/c-s Receiver with >60GHz AFE Bandwidth for 800Gb/s Optical Coherent Communications in 5nm FinFET

📋 论文概要

本文提出一款采用5nm FinFET工艺的200GS/s 8位接收机，具有超过60GHz的模拟前端带宽，实现了20fJ/c-s的能效，用于800Gb/s光相干通信。该设计解决了超高速光通信中接收机带宽与功耗的瓶颈问题。

💡 主要创新点

• 实现200GS/s超高速采样率与8位分辨率，同时保持极低功耗（20fJ/c-s），在5nm FinFET工艺下优化模拟前端带宽超过60GHz。
• 针对800Gb/s光相干通信应用，通过电路架构创新在极高数据率下维持信号完整性，降低每比特能耗。

With the recent breakthroughs in AI and the introduction of Chat GPT, data transport and interconnect fabrics of data centers are being stressed to the limits and forced to scale up even more rapidly than their traditional pace. This is leading to a throughput expansion rate that is faster than existing thermal handling capability while forcing the power form factors of
