Abstract
The detection device comprises a photodetector configured to transform an electromagnetic signal into a representative electric signal. The detection device also comprises an amplifier having a first input terminal connected to a first terminal of the photodetector. An integration capacitor is connected to the output terminal of the amplifier and to the first input terminal of the amplifier. A first source of a reference voltage is connected to a second input terminal of the amplifier. A second source of a detector voltage is connected to a second input terminal of the photodetector. The first and second voltage sources are correlated so as to correlate the noise components.
