Standard CMOS implementation of a novel,fully differential optoelectronic integrated receiver

To eliminate the limitations of a conventional differential optical receiver,a novel fully differential optoelectronic integrated receiver is proposed,including a new-type fully differential photodetector and a corresponding differential receiving circuit,where the fully differential photodetector converts the incident light into a pair of fully differential photo-currents.And a corresponding wide-bandwidth,high-sensitivity,fully differential optoelectronic integrated receiver is also implemented in a chartered 3.3 V standard 0.35 μm analog CMOS process.The measurement results show that the differential TIA integrated with a fully differential photodetector reaches a 500 Mbit/s data rate,and the whole receiver achieves a 1.098 5 GHz 3 dB bandwidth and a -12.3 dBm sensitivity at a 10-12 bit error under 850 nm incident lights.
