摘要：
An amplifier device including at least one operational amplifier, whereby a transformer is connected upstream from the input of the operational amplifier and the output signal of the operational amplifier or a signal generated from this output signal is fed back again to the input of the operational amplifier via a path with a predetermined resistance whereby the feedback signal is fed back before the input of the transformer whereby the transformer is designed or connected in a signal-inverting manner.
