Abstract
A current source circuit is characterized in that it contains a control device that controls a component of the current source circuit that determines a variable of the current supplied by the current source circuit. The component is controlled in accordance with the conditions that prevail in the unit that is supplied by the current source circuit with current. The circuit is thus capable of continuously supplying a constant current without any limitations to its applications.
