Abstract :
An optical receiver front-end for SONET OC-96 receivers was analyzed and designed in 0.18 mum CMOS process. It consists of a transimpedance amplifier (TIA) and a limiting amplifier (LA). The TIA takes a fully differential configuration, and regulated cascode (RGC) input stage is implemented. The LA was realized by five cascaded identical gain stages with active inductor load. The TIA achieved 4.2 GHz bandwidth for 0.5 pF photodiode (PD) capacitance and 1.2 kOmega transimpedance gain. The LA achieved 5.4 GHz bandwidth and 29 dB voltage gain. The optical sensitivity is -19 dBm at 5-Gb/s for a bit-error rate of 10-12, and it dissipates 45.5 mW for 1.8 V supply
