摘要
提出了一种设计高阶电流模式滤波器的新方法,即采用可变阻抗换算法对通过无源RLC设计的电流模式滤波器进行换算,这种方法能够有效地解决模拟集成滤波器中电感的制作问题。同采用回转器的方法相比,该方法能更有效地保持无源滤波器低灵敏度的特性,同时,还能够保证电路工作的精确性。
A new method for designing higherorder currentmode filter is presented in the paper, in which variable impedance conversion algorithm is used to make a conversion on currentmode filters based on passive elements This technique is effective in fabricating inductors in integrated filters Compared with the method of using gyrators, it can retain the low sensitivity of passive filters, while ensuring the operation accuracy of the circuit
