Abstract
The present invention relates to a circuit configuration (10) having a feedback operational amplifier (AMP) for amplifying an input signal (Vin) input into the circuit arrangement (10) and outputting the amplified input signal as an output signal (Vout). In order to be able to change the circuit amplification (Vout/Vin) easily and reliably in the circuit configuration (10) and simultaneously keep an impairment of the output signal (Vout) caused by noise relatively low, capacitance values (Cb, C) of the coupling path (12) and of the feedback path (14) are adjusted simultaneously to one another correlated in a special way.
