摘　　要：阐述了由电压模式有源ＲＣ滤波器导出使用电流传送器（ＣＣ）的电流模式连续时间滤波器的三种方式，即由运算放大器（ＯＡ）滤波器导出ＣＣ滤波器；由状态变量电路导出ＣＣ滤波器；由信号流图导出ＣＣ滤波器。所导出的全部电路具有与原电路相同的无源灵敏度特性。如果采用自动调谐措施，则本文所提出的电路适于集成实现。Three approacbes of filter are deliberated namely:CC(current converyer)filter de-rived from OA(operation amplifer)filter , that from state variable circuit and that from signal flow graph. They are derived from active RC filters and constructed with current conveyor instead formed the current-mode continuous-time filters.The circuits have the same passive sensitivity as that of the original one. If autocor-rection is applied,all the three being offered are suitably performed by integrated Circuit.
