A 25-Gb/s, 2.8-mW/Gb/s low power CMOS optical receiver for 100-Gb/s Ethernet solution

We demonstrate a high speed (25-Gb/s) and low power (2.8-mW/Gb/s) operation of a CMOS receiver for 100-Gb/s Ethernet, consisting of a novel transimpedance amplifier based on 65-nm CMOS technology and a back-illuminated PIN-PD.
