摘要

This work presents an Electro-Absorption Modulator (EAM) based single-mode 50Gb/s NRZ optical link in 16nm FinFET. The TX uses T-coil based over-peaking to improve modulation efficiency and relax TIA's bandwidth and noise requirement. The RX uses a 3-stage TIA with T-coils to improve BW. The link sensitivity is -10.9dBm OMA at BER <; 10 ^-12 and it consumes 4.31pJ/bit at 50Gb/s with 2dB link margin.
