摘　　要：针对反应堆功率测量前级插件的校准,设计了一种精密微电流源。该微电流源采用高精度的设计方法,使用数字化控制和软件校准,实现了0.0~200.0μA的微电流输出。测试表明：该微电流源能够稳定工作,并具有0.05%FS的步进,误差小于±0.005%FS。A precision micro-current source with a 0～200μA range is designed for calibrating of the reactor power measurement preamplifier.By means of high-precision design,digital control and software calibration,a micro-current output with a range of 0.0～200.0μA is produced.The test shows that this micro-current source performs well with a 0.05%FS stepping and error less than±0.005%FS.
