【摘要】 提出了利用电流传输器 (CCⅡ )组成滤波器的方法。适当选择无源元件就可实现各种二阶滤波函数。本电路由 1个CCⅡ和 4个无源元件综合而成。因为具有很高的输入阻抗 ,所以级联时不需缓冲级。电路中的Q值只决定于无源元件值之比 ,因此有利于集成。更多还原

【Abstract】 A filter design using second generation current conveyor (CCⅡ) is described. A variety of desired two fractional filters can be implemented by appropriate selection of passive element. The sample circuit is integrated with a single CCⅡ and four passive elements. It is not in need of buffer stage for cascading because of high input impedance. The value of Q in element is only determined by the ratio of passive element. Therefore, it is beneficial to integration.更多还原
