摘要
提出了一种基于共源共栅电流镜的CMOS电流控制电流传输器(CCCⅡ)电路。该电路由跨导线性环电路和共源共栅电流镜构成。相对于基于基本电流镜的CMOS电流控制电流传输器,该电路具有输出阻抗更大以及电流传输精度更高的优点。分析了电路的工作原理,给出了实验结果,验证了电路的正确性。
The paper presents a CMOS current controlled current conveyor（CCCII） based on cascode current mirror. The CCCII circuit is constructed by a translinear loop and eascode current mirror. Comparing with CCCII based on the simple current mirror, this circuit has the following merits： high output impedance and high current transfer accuracy. Performance principle of the circuit is analyzed and experiment results are given. The results of experiment verify the feasibility of the CCCII.
