Claim 11:
12. The current supply circuit of claim 10, wherein:
the second current mirror circuit comprises a fourth transistor and a fifth transistor; and
the compensation current generation circuit comprises:
a sixth transistor connected to a common node formed by a gate terminal of the fourth transistor and a gate terminal of the fifth transistor and configured to change an output voltage thereof based on a bypass voltage formed in the common node;
a direct current source configured to supply a direct current to one terminal of the sixth transistor; and
a third current mirror circuit configured to receive an output current of the sixth transistor and the direct current of the direct current source, to generate the compensation current, and to supply the compensation current to the first current mirror circuit.
