摘要

本文介绍了一种基于28纳米CMOS工艺的224gb /s逆变器的跨阻放大器的设计与仿真。光电二极管和CMOS TIA的协同设计有效地优化了光接收机。TIA采用分布式峰值和交错有源反馈(IAFB)技术实现带宽增强。仿真结果表明，所提出的TIA具有39-dBΩ跨阻增益和70 ghz带宽。总的来说，它实现了一个清晰的224 gb /s PAM4眼图。在0.9 v供电电压下，总功耗为20.7mW。输入参考噪声电流为8.2uArms。

A 224-Gb/s Inverter-Based TIA with Interleaved Active-Feedback and Distributed Peaking in 28-nm CMOS for Silicon Photonic Receivers

This paper presents the design and simulations of a 224-Gb/s inverter-based transimpedance amplifier (TIA) designed in 28-nm CMOS process. The co-design of the photodiode and CMOS TIA efficiently optimize the optical receiver. The TIA achieves the bandwidth enhancement with the distributed peaking and interleaved active-feedback (IAFB) technology. The simulations result show that the proposed TIA has 39-dBΩ transimpedance gain and 70-GHz bandwidth (BW). Overall, it achieves a clear 224-Gb/s PAM4 eye diagram. The total power consumption is 20.7mW at 0.9-V supply voltage. And the input referred noise current is 8.2uArms.
