PHN 9765 -7- 4-11-1980 ABSTRACT. "Integrated amplifier arrangement". An integrated amplifier arrangement in which the direct voltage gain is suppressed, which arrangement com- prises two transistors arranged as a differential pair with an output between the collectors of these transistors. In order to improve the high-frequency properties of the amplifier arrangement the collector circuit of the transis- tor includes two load transistors in cascade with the two transistors arranged as a differential pair, which each include an impedance in their base circuit in order to obtain an inductive input impedance on the emitter side of said transistors, In order to obtain direct-current and low-frequency negative feedback for eliminating the d.c. gain the base electrodes are cross-coupled to the collector electrodes of said load transistors.
