Design and realization visible light communication transmitter circuit

In this paper, the front-end transmit visible light communication circuit design are discussed. The first part focuses on the design of visible light emission circuit in response to the high speed, low power consumption characteristics of the LED light source to do a consideration, based on the detection of light intensity, respectively, the use of transistors and amplifiers transmitting circuit three programs; The second section focuses on the three circuit performance tests and the results were analyzed.
