PHD.79 138 7 8.9.80 "ABSTRACT": "Differential amplifier". A low-pass transfer is effected between the two stages in an asymmetrically driven differential amplifier, which transfer has a negative effect on -the high frequencies. The measure embodying the invention provides by means of a further transistor a negative feedback circuit which causes the low-pass filter to be of a low resistance or because of which it need only process low voltages. This greatly improves the trans- mission for high frequencies.
