Performance Analysis of the Bias Tee Circuit in Visible Light Communications

This article analyzes the performance of the bias tee circuit in visible light communications. The response of a simple bias tee circuit is studied by modifying the inductor and capacitor values, and different LED colors. The results show the best capacitor and inductor commercial values that should be placed on the bias tee circuit in order to obtain the best frequency response from LEDs of different colors. All the analysis and results explained on this paper are entirely theoretical.
