ABSTRACT:
An amplifier arrangement with a first input circuit and an output circuit, which output circuit is constituted by the series connection of the collector-emitter path of a first transistor and a diode, while the first input circuit is constituted by the series connection of a second diode and the collector-emitter path of a second transistor, whose base-emitter junction is shunted by the first diode. A second input circuit is obtained in that an input connection point is connected to the base of the second transistor. The amplifier arrangement comprises a second output circuit, which is constituted by the collector-emitter path of a third transistor, whose base is connected to the collector of the second transistor. An important application of said amplifier arrangement is as a high-frequency driver stage for a class-B push-pull output stage.
