Abstract
A control loop having an amplifier arrangement that has a variable gain is specified. The amplifier has an output for outputting a signal representing the present gain. The control loop comprises a combination unit, which combines the signal at the additional output with a threshold value in such a way as to avoid a kink in the characteristic curve in the region of the highest or lowest variable gain. The advantages of an amplifier that is voltage-linear within wide ranges can thus be united with low switching transients.
