Shengbo Eben Li · Journal of Logistical Engineering University · 2011
In order to improve the precision of constant current source,and decrease the affect of temperature to the stability of constant current source,by analyzing the low stability of constant current source,comparing constant degree of source device,a new way to improve accuracy of constant current source by using constant voltage source is proposed,the designe principles and specific circuits are put forward,and the theory analysis and design notes are given.At last,the high precision constant current source circuit is examined.The research method improves the precision of constant current souce obviously.
