Design of an Integrated Circuit for LED Driving in Visible Light Communication Applications

This paper presents the design of an integrated circuit devised to control an LED driver with visible light communication (VLC) capability. The chip was designed for a standard 0.5-μm CMOS technology and it is applied to control a buck converter. The adopted communication strategy is the variable pulse position modulation (VPPM), which allows the LEDs dimming and the data transmission at rates up to 266.6 kbit/s. The building blocks of the proposed integrated circuit are described, and SPICE simulation results are shown.
