Abstract
A receiver of a pulsed light signal comprises a photodiode adapted to generate an electric current in response to this light signal, having a parasitic capacitance Cas its characteristic; an electrical ground; and a transimpedance amplifier connected to the input of the photodiode by a linking capacitor C. It includes an attenuation pad located between the photodiode and the transimpedance amplifier, consisting of a capacitor Cwhere C=C/(α−1), α being a predetermined attenuation, where α>1.
