摘要
在电流模式电子电路设计中,电流镜是基本的电路应用部件,既可以作为偏置单位,也可以作为信号处理单位。利用OTA反馈电路实现低压、高速高精度电流镜,并用TSMC0.35μ、3.3V工艺利用pspice完成电路的仿真,结果与基本电流镜及共源共栅电流镜相比,精度较高,电压摆幅大,更适合在低压下工作。
Current mirror is a basic electric circuit application part in the field of current-mode circuit. It can be used as a bias unit or a signal to be dealt with. In recent years, many experts focus on the accuracy and lowvoltage of current mirror. This paper introduces a circuit based on the feedback of OTA to implement this current mirror and uses MOSISTSMC 0. 35μ process to simulate it with pspice. The results of the simulation illustrates that it matches the design very well.
