摘要
提出电流模式状态变量法电路的电流传送器CCII实现结构。该结构电路形式对称 ,通过外接无源元件RC之取值 ,可实现任意滤波特性。文中推导了设计公式 ,与任意滤波特性的其他CCII近似实现结构比较 ,本结构设计公式简洁 ,计算方便。举例说明了二阶低通滤波器的实现和PSPICE仿真。
A new current-mode filter structure based CCII(second generation current conveyor) is suggest to realize the circuit built in state variable method.The arbitrary filter characteristics can be realize in this structure by setting the value of passive elements connected outside.The formula used to design filter in this structure is more simple than that in other structure because this strcture is symmetrical network.An example is taken to illustrate the realization of two-order low pass filter in this structure and the process is simulated by PSPICE software.
