A transistor amplifier provided with base, emitter and collector electrodes and having, in combination, a bipolar resistant device of negative temperature coefficient, connected between the base and emitter electrodes and arranged so as to be approximately at the same temperature variations as the amplifier, a variable energy divider resistor element, means for connecting said element with said device within the amplifier input circuit, means for applying the current through a resistive circuit to the element energy divider and said device of said input circuit and through these, the resistance of said resistive circuit being high compared to the resistance that said input circuit offers to said current in view of which the variation of the effective resistance becomes possible of said device and thus produce a variation of the polarization of the amplifier simultaneously, with the compensation of the temperature variations of the amplifier and a substantially constant current through said input circuit.
