ABSTRACT:
A current stabilizing arrangement includes a first circuit having a series arrangement of a first resistor, a second resistor, and the collector-emitter path of a first transistor having its base connected to a point between the first and second resistors. A second circuit includes the collector-emitter path of a second transistor whose base is coupled to the collector of the first transistor. By providing a third resistor in the first circuit, in series with the first and second resistors and connected between the base of the second transistor and the collector of the first transistor, improved current stabilization with variations in supply voltage is obtained.
