ABSTRACT:
An amplifier arrangement has an amplifier (3) with a signal input (31), a feedback input (32) and a signal output (33). A first coupling path (FB1), which has a first impedance element (R1), connects the feedback input (32) to the signal output (33). A second coupling path (FB2) has a filter device (4), a buffer circuit (5) and a second impedance element (R2) connected in series, and connects the feedback input (32) to the signal output (33) or to the signal input (31).
