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 50×50μm2.The whole chip has an area of 1511×666μm2.The LA bandwidth is expanded by spiral inductance which has been simulated by software HFSS.The chip area is 1950×1910μm2 and the measured results demonstrate an input dynamic range of 34 dB(10–500 mVpp)with constant output swing of 500 mVpp.
