ABSTRACT:
An integrator circuit has an integrator unit performed to generate an integrated signal from a modulated input signal. Additionally, the integrator circuit has an error feedback coupler connected to an output of the integrator unit and to an input of the integrator unit and formed to determine an error component from the integrated signal or from a signal derived from the integrated signal and to compensate the error component via the feedback in the modulated input signal.
