Abstract: The characteristics and principles of a new current regulator are analysed- As A result of adopting the current regulator as the current supply and realizing the optirrium temperature compensation, a very stable output current have been obtained. The device not only has large dynamic impedance, current temperature coefficient less than or equal to 10-4/℃. but also has the advantage of continuous adjustability of output current from 1 mA to 500 mA. -
