ABSTRACT:
A device for amplifying an input signal comprising a semiconductor unit having at least one semiconductor component, and circuit for setting an operating point of the semiconductor unit. The circuit is designed such that during amplification of the input signal, an operating point of the semiconductor unit can be varied automatically and independently for a measured value, in accordance with a predetermined profile of a maximum possible signal amplitude of the input signal between a distortion-optimized setting, for high maximum possible signal amplitude and a noise-optimized setting for a low maximum possible signal amplitude.
