  • Transistorized amplification stage with improved polarization device
    Patent number: 4599577
    Abstract: 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 comparision is used as a control signal for controling a current chopping regulator supplying the polarization power for the base of the amplification transistor.
