| 摘 要： | 本文给出了高频有源滤波器的实用设计方法。根据给定的技术指标，首先设计一个基于运算放大器的RC有源原形滤波器，然后根据网络理论，将其转换成基于电流传输器（CCⅡ－）的RC有源滤波器。由于两个滤波器具有相同的传输函数以及相同的元件值，因此，基于CCⅡ－的滤波器保留了原形滤波器的优良性能。文中给出了用AD844实现的滤波器电路以及计算机模拟结果。

| Abstract: | In this paper, a method of design high frequency active filter is presented. From the given specifications, a prototype active RC filter based on operational amplifier is designed, then, the prototype is converted to CCII- based filter. The two filters have same transfer functions as well as element values, so the properties of the op-amp-based filter is conserved. A design example using AD844 and the computer simulation result are given. |
