A B S T R A C T In a transistorized amplification polarization device the polarization current of the collector of each amplification transistor of the stage is maintained at a constant value by means of a comparing circuit adapted to compare a collector polarization current image signal to a reference signal. The error signal result from such comparison is used as a control signal for controlling a current chopping regulator supplying the polarization power for the base of the amplification transistor.
