摘要

A compact 12-channel 480 Gbit/s optical receiver analogue front-end (AFE) for parallel optical transmission systems has been implemented in 0.13 μm SiGe BiCMOS technology. The transimpedance amplifier of AFE employed common-gate amplifier and negative feedback structure to decrease input impedance and broaden bandwidth. The limiting amplifier adopted modified Cherry-Hooper amplifier with active fe...
