Optical Receiver Design For Optical Communication Using Cascoded Amplifier with Inductor Peaking Technique

케스코드 증폭기와 인덕터 피킹기술을 이용한 광통신용 광 수신기의 설계

In this paper, a transimpedance optical receiver based on PIN/P-HEMT with cascoded input stage and inductor peaking technique was designed for several giga bits optical communication. Analysis of the receiver shows that cascoded input stage with inductor peaking increase bandwidth without sacrificing low frequence gain. The receiver achieved a low noise characteristic and maximally flat frequence response. It is shown that the 3-dB bandwidth of the designed receiver is 8.3 ㎓ and input equivalent noise current is as low as 16pA/√Hz to 10㎓.
