Abstract

We designed a burst mode optical receiver for 1.25Gbps PON(Passive Optical Network), fabricated it using $0.8{\mu}m$ BiCMOS foundry. We minimized the loss of the data in the front of the burst by reducing AGC(Automatic Gain Control) signal generation time using an exponential amplifier. We confirmed that AGC of the burst mode optical receiver functioned well and showed good performance in measurement. However, although the eye of the eye pattern was opened the jitter characteristic was deteriorated due to the heavy waveform distortion.

1.25Gbps PON(Passive Optical Network)용 버스트 모드 광 수신기를 설계하고 $0.8{\mu}m$ BiCMOS공정을 사용해 제작하였다. 지수함수 증폭기를 이용하여 AGC(Automatic Gain Control) 신호 생성 소요 시간을 단축시켜 버스트 앞부분의 데이터 손실을 최소화하였다. 측정결과 버스트 모드 광 수신기의 AGC 기능은 정상적으로 잘 동작하고 특성도 양호함을 확인하였다. 한편, 아이패턴의 아이는 열려있기는 하나 심한 파형 왜곡이 있고, 이로 인해 지터 특성 저하되고 있었다.
