Abstract

Eine Verstärkeranordnung weist einen Verstärker (3) mit einem Signaleingang (31), einem Rückführungseingang (32) und einem Signalausgang (33) auf. Ein erster Kopplungspfad (FB1), der ein erstes Impedanzelement (R1) aufweist, verbindet den Rückführungseingang (32) mit dem Signalausgang (33). Ein zweiter Kopplungspfad (FB2) weist eine Serienschaltung einer Filtereinrichtung (4) einer Pufferschaltung (5) und eines zweiten Impedanzelementes (R2) auf und verbindet den Rückführungseingang (32) mit dem Signalausgang (33) oder mit dem Signaleingang (31).
