ABSTRACT:
A current control circuit comprises a first transistor having its collector connected to an input current source, its emitter connected to a negative power source terminal and its base connected to a first reference current source, and a second transistor having its collector connected to an output current terminal, its emitter connected to the negative power source terminal and its base connected to a second reference current source. The bases of the first and second transistors are connected through respective resistors to the emitter of a third transistor, and the third transistor has its base connected to the collector of the first transistor and its collector connected to a positive power source terminal.
