ABSTRACT:
An amplifier arrangement includes an output amplifier stage (OA) comprising a stage input (SIN), a stage output (SOUT) which is coupled to a signal output (OUT) of the amplifier arrangement, and a capacitive element (CE) which couples the stage output (SOUT) to the stage input (SIN). A driver stage (DR) comprises a driver input (DIN) and a driver output (DOUT) which is coupled to the stage input (SIN). The driver stage (DR) is configured to generate a voltage potential at a driver output (DOUT) depending on an input current at the driver input (DIN) and to provide a charging current to the capacitive element (CE) being higher than the input current.
