摘要：
A constant current circuit including an emitter follower stage consisting of a transistor and a resistance connected in series thereto, an output stage connected in cascade with the emitter follower stage, and two diodes connected in series between the base of the transistor and an external power source, whereby a desired output current which flows through said output stage is obtained by supplying predetermined currents to the diodes and the emitter follower stage respectively.
