Abstract
An adjustable differential amplifier with transistors, in which a constant amplitude of the output voltage is achieved because, by means of a comparator circuit and based on a comparison of a fixed voltage with the rectified output voltage of the differential amplifier, the amplification thereof, characterized in that governor resistors are arranged between the emitters of the adjustable differential amplifier transistors which are governed by the comparator circuit so that the dc voltage working point of the adjustable differential amplifier is not modified.
