摘要
本文从理论上证明了有源R滤波器的综合方法都可用来综合有源C滤波器。对已有的有源滤波器电路只要进行对应的电容代换,就可得到滤波参数相同滤的有源C滤波器,并可根据已有的有源滤波器灵敏度公式直接得到对应的有源C滤波器灵敏度公式。
The paper proves that all the compositive methods of active R filter can be Used to compose active C filter in the theory.For many active R filter circuits that already known, if we change them with capacitive replacement, we may get the active C filters which filter parameters are egual but easier to be integraetd.And we can derive the sensitivity formuea of active C filter divectly according to the sensitivity formula of active R filter that known
