    Abstract: An electronic light detection circuit for detecting an intensity modulated light signal on a photosensitive element under backlight condition. The circuit comprises the photosensitive element, in particular as a light position detector for detecting a striking position of the light signal spot within a detection window, an amplifier with high input resistance connected to an output of the photosensitive element and a backlight suppression circuitry.The backlight suppression circuitry is connected to the output of the photosensitive element in parallel to the amplifier and comprises an electronic active resonator structure. The active resonator, structure is designed in such a way to provide a load impedance to an output of the photosensitive element with a low load impedance for low frequencies for suppression of natural and artificial backlight-saturation of the photosensitive element and a high load impedance at the frequency of the intensity modulated light signal.

    Abstract: Embodiments relate to photoreceivers, such as photodiodes. In one embodiment, an integrated circuit device comprises a photodiode, and an electrode arranged over or on top of the photodiode. The electrode is substantially transparent or otherwise exhibits a lower absorption rate, such that light or other radiation can pass through the electrode to the photodiode. Varying a charge applied to the electrode enables the spectral sensitivity of the underlying photodiode to be altered, tuned or otherwise adjusted.

    Abstract: An electric charge storage method is used in which a photoelectric current generated in a photodiode is stored for a predetermined time period and the stored electric charge is amplified by an amplifier to obtain an output. Further, the storage time period is switched so that an output from the circuit has a characteristic of a piecewise linear approximation of a logarithm of an illuminance, permitting a sufficient resolution even in darkness.
