Abstract
An amplifier circuit includes an amplifier input, an amplifier output, a control terminal for adjusting a gain of the amplifier circuit, and a feedback path between the amplifier output and the control terminal, wherein a variable-impedance means, the impedance of which depends on a temperature so that a variation of the gain depending on the temperature is reduced, is connected in the feedback path.
