红外遥控接收器的应用非常广泛， 而带通滤波器是红外遥控接收器芯片中的一个重要的模块。滤波器的实现通常需要电感，而电感是很难集成到集成电路中的， 本文介绍一种利用放大器和电容实现有源电感的方法。关键词: 红外接收器、带通滤波器、有源电感Design of Band Pass Filter Using in Infrared Remote ReceiverHan LiangMicro-electronic center of Harbin Institute of Technology at Wei HaiWei Hai, China 264029Email: hanliang@hit.edu.cnAbstractThe application of infrared remote receiver is very abroad, while band pass filter is animportant module of infrared remote receiver chip. The implementation of band pass filter usually院needs inductor, which is very difficult to integrate in IC. In this paper, we introduce a method using amplifier and capacitor to implement active inductor.Keywords: Infrared Remote Receiver, Band Pass Filter, Active Inductor
