In this paper, we designed a new type of high precision 1 μA constant current source after deeply studying the high precision precise dc constant current source. Compared with the traditional constant current source, in this paper we adopted complex amplifier added with floating power supply outside to design high precision dc constant current source which is for China's space use , its output current is 1 μA, resolution is 0.1 nA, accuracy is 0.5. This high precise dc constant current source is mainly used for new model rocket engine performance testing in aerospace, but also can be widely applied in different fields in need of precision measurement.
