A monolithically integrated optical receiver,including the photodetector,has been realized in Chartered 0.35 μm EEPROM CMOS technology for 850 nm optical communication.The optical receiver consists of a differential photodetector,a differential transimpedance amplifier,three limiting amplifiers and an output circuit.The experiment results show that the receiver achieves an 875 MHz 3 dB bandwidth,and a data rate of 1.5 Gb/s is achieved at a bit-error-rate of 10 -9.The chip dissipates 60 mW under a single 3.3 V supply.
