CMOS Technology Scaling Considerations for Multi-Gbps Optical Receivers With Int

Abstract

The integration of photodetectors for optical com- munication into standard nanoscale CMOS process technologies can enable low cost for emerging high volume short-reach parallel optical communication. Whereas past work has highlighted the challenges that face integrated photodetectors in highly sca led CMOS technologies, this work e xamines the opportunities af- forded by these new technologies. First, scaling promises improved extrinsic photodetector bandwidth thanks to improved TIA p er- forma
