Electric circuitry for baseline restoration

An electric circuitry for baseline restoration, comprising:

• an input terminal to receive an input signal having pulses above or below a baseline level,
• a baseline sampling circuit for providing a baseline output signal representing a baseline level of the input signal,
• an integrator circuit to receive an error signal representing an error of the baseline level of the input signal, the integrator circuit being configured to provide an integrator output signal being a representation of an integration of the error signal,
• a digitization circuit to provide a digital output signal being a digital representation of the integrator output signal,
• an output stage to provide a baseline restoration output signal representing a corrected baseline level of the input signal, the output stage being configured to provide the baseline restoration output signal in dependence on the digital output signal.
