A Novel Transimpedance Amplifier for 10 Gbit/s Optical Communication System

摘要：

A novel wideband CMOS Regulated Cascode (RGC) transimpedance amplifier, which can be used in the front-end of 10 Gb/s optical communication system, is implemented using a 0.18 μm CMOS process. Resistive feedback, source follower and capacitive degeneration techniques are used to increase bandwidth. A converter with single-ended input and differential-output is used to connect to the next stage. The simulation results show that the transimpedance gain is 40 dBΩ., the bandwidth is 8.69 GHz and the average noise current spectral density is 96.48 pA/ (Hz) . The output eye-diagram voltage amplitude is 2.05 mV when the input current magnitude is 50 μA.
