A 2.5Gb/s O.38mm2 Optical Receiver with Integrated Photodiodes in O.18f.lm CMOS SOl

In this work, we report an optical receiver with integrated photodiodes operating at 850nm wavelength. The receiver achieves a data-rate of 2.5Gb/s without using any equalizer. To minimize the area, no inductors are used in the design. The entire receiver occupies an area of O.38mm2• This represents the smallest optical receiver operating at the Gb/s regime. The chip is fabricated in O.18J.lm CMOS SOl process technology. Index Terms Optical Receiver, Integrated Photodiode, CMOS, Silicon Process.
