Die Transistoren (T1 -j- T2) auch abnehmen. Es wird somit Erfindung bezweckt, einen Verstärker mit hoher io ein Maximalwert für die Gesamtsteilheit der Tran-Steilheit und/oder niedrigem Klirrfaktor zu schaffen, sistoren (T1 + T2) als Funktion des Widerstandes R der geeignet ist, um als integrierte Schaltung ausgeführt gefunden. In F i g. 2 ist dieses Verhalten der Gesamtzu werden.

At least equal to 1), with an output electrode if, on the other hand, the resistance R of the field effect transistor and an input electrode 5 are so small that this is galvanically comparable with the internal resistance of the layer transistor T 2 following it, the first layer transistor so will also be connected. In known circuits of this type, the <x 'of the above-mentioned layer transistor is strongly separated from the source of the field effect transistor with the base, and the overall steepness of the electrode of the first layer transistor is connected with this. The transistors (T 1 -j- T 2 ) also decrease. The aim of the invention is thus to create an amplifier with a high io maximum value for the overall steepness of the Tran steepness and / or low distortion factor, sistors (T 1 + T 2 ) as a function of the resistance R which is suitable to be implemented as an integrated circuit found. In Fig. 2 this behavior is to become the overall. Slope as a function of the resistance R through the
