Sample Text
In this paper, the applicability of photodiode structures, which are realized with standard CMOS production processes and can be integrated into microelectronic systems at low costs, to optical communication systems, is examined. A photodiode with an area of 1.05 mm × 1.00 mm, implemented with UMC 180 nm standard CMOS production on a silicon substrate, was tested as an optical receiver in a setup where Power LEDs of different visible wavelengths were used as sources. The performance of the CMOS photodiode was compared to that of a Thorlabs PDA10A-EC photodiode used as a reference. In experiments, it was seen that the transmission bandwidth of the reference photodiode was in the range of 0.87 - 1.68 MHz, and the CMOS photodiode could reach bands with comparable values of 0.70 - 1.37 MHz. A square wave signal at a frequency of 200 kHz can be transmitted without significant distortion in an optical communication system using CMOS photodiodes. In this work, applicability to the optical communication systems of photodiodes realized with standard CMOS fabrication processes, which can be integrated to microelectronic systems at low costs. A photodiode fabricated with UMC 180 nm standard CMOS process on a silicon substrate within a 1.05 mm × 1.00 mm area is experimented with as an optical receiver in a setup where LEDs of different visible wavelengths are used as sources. Performance of the CMOS photodiode was compared to that of a Thorlabs PDA10A-EC photodiode used as a reference. In the experiments, it was observed that the communication bandwidth of the reference photodiode is in the 0.87-1.68 MHz range and that the CMOS photodiode can achieve comparable bandwidths in the range of 0.70-1.37 MHz. A square wave of 200 kHz frequency can be carried via an optical communication system using the CMOS photodiode without suffering from significant distortions.
