Investigation of hardware equalizer based on a bridged-T network for high-speed VLC

This paper comprehensively investigates a bridged-T pre-equalizer circuit (BTEC) designed for a highspeed visible light communication (VLC) system. The circuit is intended to mitigate the bandwidth limitation of light-emitting diodes (LEDs) in the VLC system. We integrate the advanced design system...
