Demo: 112 Gbps 4-PAM 16nm FinFET CMOS TIA 

Measurement of a prototype transimpedance amplifier (TIA) implemented in 16nm FinFET CMOS and co-packaged with a photodiode operating at 112Gbps. This TIA is suitable for 4-PAM optical communication. Optical measurements at 1310nm are shown. Full details of this work were presented at CICC in April 2022.
