摘要
提出了二阶OTA—C滤波器的一般设计方法。给出了设计实例和实验结果,并对带阻(OTA—C)滤波器的阻带衷减在ω_O处为有限值的原因进行了研究,提出了相应的补偿方案。
A generalized design method of second—order OTA—C filters is presented. Design examples and experimental results are given and the reason that stop—band attenuation of band—stop(OTA—C) filter is not infinte at notch frequency ω_0 is investigated. A corresponding compensation method has been presented.
