该论文提出了一种用于可见光通信应用的无电感AC输入LED驱动器，实现了8Mb/s的数据传输速率和6.4%的低频纹波。解决了传统LED驱动器难以支持高速调制的问题。
Light-emitting diodes (LEDs) are becoming the dominant lighting source over their conventional counterparts. Besides the benefits of high efficiency and long lifetime, LEDs also show great potential for high-speed data transmission because of their wide bandwidth (BW). In addition to offering general lighting, the light output can be modulated with fast-switched LEDs to achieve visible light communication (VLC). Though over 100Mb/s data-rate has been demonstrated with white LEDs in the laboratory, the high-frequency modulation is hardly supported by commonly used dimmable drivers with switching converters to regulate LED current. In these drivers, the changing slope of LED current is limited by both low loop BW and large inductors and capacitors [1]. The linear multiplestring LED drivers [2], free of inductors and big capacitors, theoretically can provide higher turn on/off speed. However, the light output of these drivers usually
