Abstract :
An optical receiver designed and fabricated in 0.25 mum ultra-thin silicon (UTSi) on sapphire technology is flip-chip integrated with p-i-n photodiodes. The receiver includes a transimpedance amplifier (TIA), limiting amplifiers (LA), and an output buffer. The power consumption of the TIA and limiting amplifiers is 67.3 mW. The receiver is shown operating with a gain of 57 dBOmega at a bit rate of 10 Gb/s. The measured sensitivity is -1.7 dBm for a bit error rate of 10-9. This is the first 0.25 mum CMOS TIA and LA codesign that operates optically at 10 Gb/s.
