Design of photo-detector circuit for fiber optical sensor / Nurul Iliana Bakhari

The optical sensor might utilize visible light, infrared, LED or laser to propagate communication data. The light ray was then sent to any light detection and conversion devices. In this project, we use photodiode to analyze the light signal rather than optical spectrum analyser (OSA). Thus, InGaAs...
