Abstract
An amplifier is described which amplifies an input signal according to a defined amplification factor, and which generates an output signal. To reduce an offset fraction of the output signal the amplifier comprises a feedback path which has lowpass characteristics and which returns the output signal in a lowpass-filtered state to an input of the amplifier. The feedback path comprises an amplifier stage as well as at least one Miller capacitance connected between an input and an output of the amplifier stage.
