Abstract
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.
