ABSTRACT:
A current supply circuit includes a current source producing a first current, a current amplifying circuit for producing a second current having a magnitude a.multidot.I/h.sub.FE from the first current where a is a constant, I is a magnitude of the first current and h.sub.FE is a current transfer ratio of a current supply circuit. The above current supply circuit produces a third current from the second current so that the third current has a magnitude equal to a.multidot.I.
