Abstract
In this study, photo-darlingtons have been developed by using standard CMOS process for visible light communication. The practical application of the photo-transistors is focus for visible light ID which uses the carrier frequency of 28.8kHz. The response sensitivities of photo-darlington was 9times higher than that of typical PIN photo-diode, and the response frequency was 110kHz.
