摘要
提出了1种基于第2代正相电流传送器(CCII+)的n阶电压模式多环反馈(multiple-loop feedback,简称MF)低通滤波器的系统设计方法,推导出了系统的设计公式.利用该方法可产生出n阶不同结构的低通滤波器.以3阶低通滤波器为例阐述了设计过程,并用PSPICE进行仿真分析,设计和仿真结果表明,系统设计理论正确,设计方法可行.
A systematic method of designing for n th-order voltage-mode multiple-loop feedback low-pass filter based on CCII ＋ is presented. The systematic design formula is derivatived. Different finds of nth-order low-pass filter structure are obtained by this method. An third-order low-pass filter is designed through the proposed method and simulated in PSPICE. The simulation results show that the proposed design method is feasible.
