AMPLIFIER ARRANGEMENT AND METHOD FOR AMPLIFYING A SIGNAL

摘要

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