Fully differential optoelectronic integrated receiver implemented by 0.35μm standard CMOS process

A high-bandwidth,high-sensitivity fully differential optoelectronic integrated receiver is implemented in a chartered 3.3V standard 0.35μm analog CMOS process. To convert the incident light into a pair of fully differential photo-currents,a novel fully differential photodetector is proposed,which is composed of two completely identical photodiodes. The mea-surement results show that the receiver achieves a 1.11GHz 3dB bandwidth and a -13dBm sensitivity for a 10-12 bit error at 1.5Gb/s data rate under illumination by 850 nm incident lights.
