A 3.125 Gbps CMOS fully integrated optical receiver with adaptive analog equalizer

This paper presents the design of a 3.125 Gbps monolithic CMOS optical receiver, integrating a photo detector, a transimpedance amplifier, and a post limiting amplifier on a single chip. The optical receiver is capable of delivering 420 inV
_pp
to 50 Omega output load after optical to electrical conversion. High speed operation is achieved by utilizing spatial modulated light (SiVIL) detector and adaptive analog equalizer. Implemented in a 0.18 mum CMOS technology, the total power dissipation is 175 mW. The chip size is 0.7 mm
