Verstärkereinrichtung mit veränderbarer Arbeitspunkteinstellung sowie Verwendung der Verstärkereinrichtung

摘要

The invention relates to an amplifier device (10) serving to amplify an input signal (S1) and comprising a semiconductor unit (100) presenting at least one semiconductor element and means (200) for controlling the operating point of the semiconductor unit (100). The means (200) are configured in such a way that during amplification of the input signal (S1) an operating point of the semiconductor unit (100) can automatically be adjusted, in the absence of measured values and in accordance with a set curve of a maximum possible signal amplitude of the input signal (S1), between a distortion-optimization setting for a high maximum possible signal amplitude and a noise-optimization setting for a low maximum possible signal amplitude.
