An integrated circuit comprising circuits such as current mirror circuits, and designed to supply a current from a current source to a load. The circuit comprises two current mirror circuits, two transistors, a current source, and a load. Either current mirror circuit has a power-supply terminal, an input terminal and an output terminal. Either transistor has two ends and an input terminal. The current source has two ends, an the load also has two ends. The current source is connected at the first end to a first power source, and at the second end to the input terminal of the first transistor. The first transistor is coupled at the first end to a second power source, and at the second end to the input terminal of the first current mirror circuit. The first current mirror circuit has its power-supply terminal coupled to the first power source, and its output terminal coupled to the input terminal of the second current mirror circuit. The second current mirror circuit has its power-supply terminal coupled to the second power source, and its output terminal coupled to the node of the input terminal of the first transistor and the second end of said current source. The second transistor has its input terminal connected so that of the first transistor, its first end coupled to the second power source, and its second end connected to the first end of the load. The other end of the load is coupled to the first power source.
