| Summary: | 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. |
