ispPAC器件在滤波器设计中的应用

The Application of ispPAC Device into Filter Designing

介绍了在系统可编程模拟电路(ispPAC)的结构、性能特点和发展前景,阐述了用ispPAC器件实现滤波器的设计思想和方法。利用ispPAC10、ispPAC80,借助于PAC-Designer开发软件,能够分别实现二阶、四阶、五阶低通滤波器。这种设计不需外接电阻、电容和运算放大器等元件,方法简单、快捷,修改方便。通过仿真和下载验证表明设计具有较好的级联、“重构”电路和可编程性能。

The article introduces the structure, function and perspective of ispPAC, and then explains the principles and methods Of filter designing with ispPAC device. Assisted by PAC -Designer, ispPAC10 and ispPAC80 can be used to develop software to bring about respectively the second order, fourth order and fifth order low pass filter. The components such as extra resistance, capacitance, operational amplifier, etc are not required in the designing, which is easy, fast and flexible in revising. Through the validation of emulating and downloading, the designing proves to have much better cascade, reconfiguration circuit and program function.
