摘要
通过对任意阶无漂移全极点有源低通滤波器多参数灵敏度的分析,证明系统总的Schoeffler灵敏度与设计中自由变量的取值无关.并据此导出了该类无漂移有源低通滤波器参数设计的最简形式,使得计算公式大为简化,同时使元件种类减少一半.
Through analyzing the Schoeffler multi-parameter sensitivity of the non-drift all-pole active low-pass filters, the paper proves that there is no relationship between the multi-parameter sensitivity and the free variables used for designing. As the results, the simplest design formulas of the system are proposed and the number of the kinds of the needed elements has been reduced to the half.
