Abstract
In one embodiment, an ambient light sensor with first and second photo-detectors is disclosed. The first and second photo-detectors may have different depths and respond differently to light having a specific wavelength. The ambient lights sensor may further comprise a circuit configured to detect light of a specific wavelength. In another embodiment, the first and second photo-detectors may be configured such that each of the first and second photo-detectors detects coupling current from each other. In yet another embodiment, in addition to the first and second photo-detectors, a third photo-detector may be formed proximate to at least one of the first and second photo-detectors such that coupling photo-current is detected therein by the at least one of the first and second photo-detectors.
