Abstract :
A 12-channel, 30Gb/s monolithic integrated front-end amplifier for parallel optical communication application is presented in this paper. The chip was designed and fabricated in 0.18-μm CMOS technology. The capacitance of photodiode is 2pF, each channel is designed to work at 2.5Gb/s and contains a trans-impedance amplifier (TIA) and a limiting amplifier (LA). With the power supply of 1.8V, each channel consumes 85mW, and provides 578 mV differential outputs. Total power consumption of 12 channels is about 1.02W. Details of the chip design, layout and measured results are described below.
