In this work, a 12-channel 120-Gb/s optical receiver array is realized in a 0.18-?m CMOS process. Optical receiver array consists of transimpedance amplifier (TIA) and limiting amplifier (LA). To enhance the bandwidth without deterioration of the other performance, advanced common-gate input configuration, active feedback technique, and negative impedance compensation are exploited. Post-layout simulations demonstrate that a single channel optical receiver achieves 96-dBO transimpedance gain (Z_T), 10-Gb/s operations with 7.1-GHz bandwidth for 0.5-pF photodiode capacitance, and -20-dBm optical sensitivity.
