Abstract

The technology of optical-fiber systems is advancing rapidly. Parallel to the development of long-haul telecommunication systems in the gigabits per second data rates operating in the long-wavelength region is the wide penetration of optical-fiber systems in local area networks, video trunking and distribution, sensors, etc. These diversified applications impose different and often conflicting constraints on the optical receiver. The weakest signal level determined at the front-end receiver and it should be improved by appropriate design. The optimum receiver performance can be achieved depends on the devices and design techniques used. This project reexamines the optical receiver design using several method which is applying the basic transimpedance amplifier, cascade transimpedance amplifier and multiple gain stage transimpedance amplifier method. The receiver amplifier design will be simulate using existing Software such as P-spice and Micro-Cap, and then the design will be fabricated as a prototype circuit. Cascade Transimpedance Amplifier method achieved 4.568MHz for the cutoff frequency, while the Multiple Stage Gain Transimpedance Amplifier method achieved 4.4956MHz. Transimpedance Amplifier using BJT transistor method with a cascade connection and feedback structure technique achieved the objective of project to enhance the bandwidth for front-end receiver in the range of approximately in Giga Hertz which is 1.189 GHz.
