高速、高灵敏度的光接收机是传输速率达到Gb/s的长距离光纤通信系统不可缺少的器件。近年来，光电集成电路（OEIC）光接收机以其相对于传统光接收机具有寄生效应最小、成本低、可靠性高、体积小等优点而受到越来越多的关注。提出了一种基于inp的共享层结构PIN/HBT OEIC光接收机前置放大器的设计方法。作为前置放大器设计的基础，研究了HBT大信号模型（GP模型），并对模型参数进行了提取和优化。所提取的GP模型与HBT的实测特征吻合较好。基于该GP模型，设计制作了具有良好高频特性的前置放大器，其- 3dB带宽可达2.0 GHz。
Optical receiver of high speed and high sensitivity is indispensable for long distance fiber-optic communication systems of transmitting rate up to Gb/s. In recent years, OEIC (Optoelectronic Integrated Circuits) optical receiver has attracted more and more attention for its advantages over conventional optical receiver such as minimized parasitics, lower cost, higher reliability and compact size. In this paper, design of preamplifier for InP-based PIN/HBT OEIC optical receiver with share layer structure was presented. As a basis for design of preamplifier, HBT large signal model (GP model) was investigated and model parameters were extracted and optimized. The extracted GP model shows a good agreement with measured characteristics of HBT fabricated. Based on this GP model, the preamplifier was designed and fabricated which exhibits good high-frequency characteristics of −3dB bandwidth is up to 2.0 GHz.
