本文提出并探讨了有源KC滤波器特性及实验结果;表明在几十千赫到上兆赫频段内,有源LC有显著的特点,特别是运算放大器的有限增益对性能影响很小,拓宽了运放的工作频段.
In this paper, the characteristics and experimental results of active KC filters are presented and discussed. The results show that the active LCs have significant features in the tens of kilohertz to the upper megahertz bands. In particular, the limited gain of the op amp has little effect on the performance and broadens Op amp working band.
