ABSTRACT:
A device for controlling a current to a load by means of mirroring is described. Two transistor units are connected to a common reference point. By driving a current through one of the transistor units, a corresponding current is generated in the second transistor unit. A control unit, connected between the transistors can regulate a voltage difference between transistors. Accordingly, the size of the load attached is determined through mirroring with accuracy and minimal power loss.
