An 18-Gb/s Fully Integrated Optical Receiver With Adaptive Cascaded Equalizer

An 18-Gb/s fully integrated optoelectronic integrated circuit for short-distance communications is realized in the TSMC 65-nm CMOS process. The system consists of a CMOS on-chip photodetector, an inverter-based cascode transimpedance amplifier, a DC offset cancellation buffer, a main amplifier, a three-stage tunable continuous-time linear equalizer, a two-stage modified limiting amplifier, a DC of...
