摘　　要：针对传统带通滤波器电路结构复杂的问题,提出一种基于电流控制传输器(CCCII)的电流模式二阶带通滤波器电路。该电路由一个CCCII和3个接地RC元件构成,可通过调节偏置电流控制电路的中心频率,具有结构简单,方便集成的特点,并且具有很低的灵敏度。使用Hspice软件对电路进行仿真,验证了该设计的正确性。According to the fact that traditional bandpass filter circuit has a complex structure, a current-mode second-order bandpass filter based on the second-generation current-controlled current conveyor（CCCII） is presented. The circuit consists of one CCCII and three grounded R and C components. The central frequency can be controlled by adjusting the bias current. The circuit has a simple structure, very low sensitivity, and easy to integrate. Hspice simulation result is given to confirm the theoretical analysis.
