摘　　要：提出一种基于第三代电流传输器(CCⅢ)的电流模式二阶滤波器的实现方法,导出的电流模式连续时间二阶滤波器结构比较简单,可实现低通、高通、带通3种滤波。这3种滤波的无源和有源灵敏度较低。本文提出的电路基于TMSC 0.35μm CMOS工艺,在2.5V电源电压工作条件下,采用Hspice在LEVEL49模型参数下对整个电路进行仿真。In this paper, we propose a realization method of the current-mode second-order filter which is based on the third generation current conveyor（CCIII）.For this the current-mode continuous-time second-order filter structure which is derived relatively simple,then can carry out three kinds of filtering：low pass, high pass and band pass. The three kinds of filtering have low passive and low active sensitivity. The proposed circuit simulated with the LEVEL49 of HSPICE and powered with 2.5 V based on TMSC 0.35μm CMOS process parameters.
