摘要

This paper reports the first fully integrated transmitter designed in an 180nm BCD process for light-emitting diode (LED) based visible light communication (VLC) and positioning (VLP) systems. The transmitter consists of Manchester coder, precision voltage and current reference, multistage Cherry-Hooper amplifier, PLL, filter and LED driver. A feed-forward equalizer is used to boost the LED bandwidth for high data rate wireless streaming. Measurement shows that, driving commercial LED lighting devices, the transmitter can stream data over light at a speed of at least 12MHz.
