本文讨论高Q二次带通有源滤波器的幅度特性,它随频率增加而增加,这主要是由放大器的有限增益带宽积造成的,最后讨论了频率补偿方法和挑选运算放大器的准则。
This article discusses the amplitude characteristics of a high Q quadband pass filter, which increases with increasing frequency. This is mainly due to the finite gain bandwidth product of the amplifier. Finally, the frequency compensation method and the criteria for selecting the op amp are discussed.
