基于MOCCCⅡ-C的n阶电流模式椭圆滤波器

N th-order current mode elliptic filter based on MOCCCⅡ-C

  • 摘要: 通过对任意奇数阶电流模式滤波器传递函数进行数学分析,将其分解为n个无损积分器级联的形式,并根据椭圆型滤波器的传输函数对输出电流信号进行线性组合,从而提出了1种奇数阶的电流模式椭圆滤波器的系统综合法.由该方法实现的电路结构简单,仅由(3n-1)/2个有源器件,n个接地电容构成.面向实际电路完成Pspice仿真,结果表明由该方法产生的滤波器具有良好的性能.

     

    Abstract: It is presented new general synthesis method for a arbitrary odd-order current mode elliptic filter based on MOCCCⅡ.The method is based on analyzing a transfer function,then generating n number of realizable transfer functions using lossless integrators and combining linearly the integrators′ output currents to meet the transfer function of elliptic filter.The filter structure presented simply only contains(3n-1)/2 active elements and n grounded capacitors.Pspice simulation for actual circuit is conducted,and the result shows that the presented circuit is of excellent performance.
