The invention relates to a light-ray detection circuit comprises a light detector (1). The light detector (1) is coupled to three capacitors (C1, C2, C3) by means of three switches. The capacitors (C1, C2, C3) are mounted in parallel such as to form a capacitive load (4), the electrical capacitance value of which varies depending on whether the switches are on or off. Said configuration makes it possible to stabilize the voltage present on the output terminal (S) of the detection circuit, thus subjecting the light detector to a wider range of illumination. |
