光接收机的设计是一个复杂的课题,珀松尼克(Personick)和戈尔(Goell)的研究己使这种设计最佳化。本文利用珀松尼克和戈尔关于光纤通信系统接收机的设计方法,研究了长波长光接收机的设计技术和光接收机灵敏度的理论计算,并进行了采用PIN-FET集成前放光接收器和分立元件PIN互阻抗前置放大器的实验。实验结果表明,PIN-FET集成组件具有较高灵敏度、电路简单和高可靠性的的优点。 The design of optical receivers is a complex subject, and research by Personick and Goell has optimized this design. In this paper, the design method of long wavelength optical receiver and the theoretical calculation of optical receiver sensitivity are studied by using the design method of Porsonik and Gore on the receiver of optical fiber communication system. Experiments on PIN Transimpedance Preamplifier for Discrete Components. The experimental results show that the PIN-FET integrated package has the advantages of high sensitivity, simple circuit and high reliability.
