Patent ID: 7834694

Claim:
A differential current mirror circuit comprising: a first current input terminal through which a current including an in-phase component and a differential component flows; a second current input terminal through which a current including an in-phase component and a differential component flows; a first branching unit that branches the current through the first current input terminal to a first current path and a second current path; a second branching unit that branches the current through the second current input terminal to a third current path and a fourth current path; a fifth current path that is connected to the second current path and the fourth current path; a first current source that allows an in-phase component current to flow through the first current path based on a current through the fifth current path; a sixth current path through which a current through the first current path minus the current allowed to flow by the first current source flows; a first current output terminal through which a current flows based on the current through the sixth current path; a second current source that allows an in-phase component current to flow through the third current path based on the current through the fifth current path; a seventh current path through which a current through the third current path minus the current allowed to flow by the second current source flows; and a second current output terminal through which a current flows based on the current through the seventh current path.
