DC constant current power supply circuit based on current closed-loop feedback control is brought (forward) in this paper and how to design the circuit is also emphatically introduced.

开发了一种基于电流闭环反馈控制的数控直流恒流源，介绍了该电路的设计思路。

The detection circuit has a major influence on the accuracy and sensitivity of DC sensor based on magnetic potential self-balance and feedback compensation.

在磁势自平衡回馈补偿式直流传感器中，检测补偿回路对系统的精度有很大影响。
