A New 10 Gb/s Optical Receiver Using Active Inductor in 90 nm CMOS Technology

This paper presents the design of a new low-power 10 Gb/s CMOS optical receiver in 90nm consisting of a transimpedance amplifier and two stages of a limiting amplifier. The transimpedance amplifier consists of two stages, and has a transimpedance gain of 54.8 $\mathbf{dB}\mathbf{\Omega}$ and −3 dB bandwidth of 8 GHz for 0.15 pF input capacitance while dissipating 4.64 mW. The two-stage limiting amplifier employs a differential topology with active feedback. The complete optical receiver has a gain of 82.6 $\mathbf{dB}\mathbf{\Omega}$ , bandwidth of 8 GHz and consumes 13.64 mW from a 1-V supply.
