摘　　要：第三代电流传输器CCⅢ(The Third Generation Current Conveyor)的基本模型由于采用基本电流镜,使得电路的DC和AC性能偏低。本文采用不同于原电路的电流镜结构,应用共源共栅电流镜和改进共源共栅电流镜(改进共源共栅电流镜具有较大的输出阻抗)提出了一种高性能电流传输器电路结构。Because of the basic current mirror used in structure of the conventional CCIII, its DC and AC performances are low. In this paper, we used the current mirror that different from the basic structure. Apply the cascade current mirrors and the proposed cascade current mirrors ,which provided high output impendence. Based on the two cascade mirrors we provided a high performance current conveyor structure.

关 键 词：电流传输器 电流模式 共源共栅电流镜
