摘　　要：本文提出一种“Q倍增带阻结构”来实现有源RC高Q二阶带阻电路.给出了设计和实验结果.由于这种新结构采用负反馈,所以有好的灵敏度特性.其实现电路也较其它高Q带阻电路简单.具有很好的实用价值.In this paper, a new structure called 'Q-multiplier bandstop structure' is proposed for the realization of second-order high-Q RC bandstop filter. A design example and experimental results are given. As negtive feedback is used, the new struccture has low sensitivity. The circuit is also simpler than others and has great practicability.
