Abstract

In a display signal amplifier arrangement, a current-sensing circuit (S) measures a supply current of an amplifier (A) to obtain a control signal (CTRL) for a bandwidth-reducing circuit (BRC) preceding the amplifier (A), where the bandwidth-reducing circuit (BRC) adaptively attenuates a high-frequency part of the display signal in dependence upon the supply current.
