摘要：

A Numerically Controlled constant-current source is designed. A negative feedback of closed-loop is used in the source based on Single Chip Microcomputer. The system has a small ripple current and reliable step-adjustable function. The setting and the output are precise. The output of the constant-current source is stable when the load is changed. The errors can reach the level of 0.1%.
