摘　　要：滤波器是光纤传感器信息处理系统的重要单元,其性能直接影响系统灵敏度。传统的有源滤波器主要由电阻、电容和运算放大器组成,体积大,元件多,而且调试不方便。本文提出了一种采用MAX274芯片的集成高阶滤波器的设计方法,所设计的滤波器能满足光纤传感器信息处理系统的高性能、易调试和小型化的要求。Filter is an important unit of optical fiber sensor information processing system, and its performance directly affects the system＇s sensitivity. Traditional active filters are composed of resistors, capaci tors, and operational amplifiers. They have greater bulk, more elements, and are more difficult to debug. In this paper, the design method of integrated high-order filter is presented using MAX274. The proposed filter can satisfy the requirement of optical fiber sensor information processing system which has the advantages of high-performance, easy regulation, and miniaturization.
