摘要
提出了一种适用于40纳米CMOS光通信的80gb /s PAM-4变增益跨阻放大器。采用多种感应峰值技术来提高可调级联码(RGC) TIA的带宽。仿真结果表明，在低增益模式和高增益模式下，分别实现了35.8 db \Omega$和34.3 ghz带宽的跨阻增益和47.1 db \Omega$。
A PAM-480-Gb/s Variable-Gain Transimpedance Amplifier in 40-nm CMOS Technology
This paper presents an 80-Gb/s PAM-4 variable-gain transimpedance amplifier (TIA) suitable for optical communications in 40-nm CMOS. Multiple inductive peaking techniques are employed to boost the bandwidth of the regulated cascode (RGC) TIA. The simulation results achieve $ 35.8-dB\Omega$ transimpedance gain with 29.6-GHz bandwidth at low-gain mode and $ 47.1-dB\Omega$ transimpedance gain with 34.3-GHz bandwidth at high-gain mode, respectively.
