Abstract
The application of infrared remote receiver is very abroad, while band pass filter is an
important 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
