单电流传输器实现的Q增强二阶带通滤波器
REALIZATION OF NEW ENHANCED Q SECOND-ORDER BANDPASS FILTERS USING A SINGLE CURRENT CONVEYER
-
摘要: 本文提出了几种用单块电流传输器(CCII)实现的Q增强二阶带通滤波电路。这些电路使用的元件较已见报道的同类电路和用运算放大器(OA)实现的同类电路少;适当选择元件参数,还可实现RCD串联谐振器。Abstract: This paper describes some new active bandpass filters using only a single second-generation current cenveyer (CCII), which are superior to early realizations for using fewer components. By choosing proper values of the circuit elements, they can be also used to simulate RCD series resonators.
