摘　　要：为了实现可见光传输信号的接收,并尽可能减小接收机的体积,适应不同亮度下的传输,利用0.18μm CMOS工艺,自主设计光探测器、跨阻放大器、主放大器并集成于一片,形成单片集成的可变增益光接收机。经过软件模拟,激光入射测试以及实地的配合由可见光控制的智能家具系统的测试,证明该接收机拥有良好的接收效果并能适应可见光的低传输速率,且有较大的输入动态范围。In order to realize the visible light transmission signal reception, minimize the volume of the receiver and adapt to the transmission under different brightness, optical detector, transimpedance amplifier and main amplifier were designed on the basis of 0.18 μm CMOS technology, and was integrated into one chip to make a visible light receiver. The software simula- tion, the laser incident test and the test of the intelligent furniture system controled by visible light prove that this receiver has a good reception effect and wide input dynamic range, and can adapt to visible light＇s low frequency transmission.
