摘　　要：A 10 Gb/s OEIC（optoelectronic integrated circuit）optical receiver front-end has been studied and fabricated based on theφ-76 mm GaAs PHEMT process;this is the first time that a limiting amplifier（LA）has been designed and realized using depletion mode PHEMT.An OEIC optical receiver front-end mode composed of an MSM photodiode and a current mode transimpedance amplifier（TIA）has been established and optimized by simu- lation software ATLAS.The photodiode has a bandwidth of 10 GHz,a capacitance of 3 fF/μm and a photosensitive area of 50×50μm^2.The whole chip has an area of 1511×666μm^2.The LA bandwidth is expanded by spiral inductance which has been simulated by software HFSS.The chip area is 1950×1910μm^2 and the measured results demonstrate an input dynamic range of 34 dB（10–500 mVpp）with constant output swing of 500 mVpp.A 10 Gb/s OEIC（optoelectronic integrated circuit）optical receiver front-end has been studied and fabricated based on theφ-76 mm GaAs PHEMT process;this is the first time that a limiting amplifier（LA）has been designed and realized using depletion mode PHEMT.An OEIC optical receiver front-end mode composed of an MSM photodiode and a current mode transimpedance amplifier（TIA）has been established and optimized by simu- lation software ATLAS.The photodiode has a bandwidth of 10 GHz,a capacitance of 3 fF/μm and a photosensitive area of 50×50μm^2.The whole chip has an area of 1511×666μm^2.The LA bandwidth is expanded by spiral inductance which has been simulated by software HFSS.The chip area is 1950×1910μm^2 and the measured results demonstrate an input dynamic range of 34 dB（10–500 mVpp）with constant output swing of 500 mVpp.
