    摘要： Embodiments of the present invention are directed to light sensors, that primarily respond to visible light while suppressing infrared light. Such sensors are especially useful as ambient light sensors because such sensors can be used to provide a spectral response similar to that of a human eye. Embodiments of the present invention are also directed to methods of providing such light sensors, and methods for using such light sensors.

    摘要： A CMOS light detector configured to detect specific wavelengths of light includes a first sensor and a second sensor. The first sensor includes CMOS photocells that are covered by a colored filter layer of a first color that has a first transmittance that allows both light of the specific wavelengths and light of other wavelengths to pass. The second sensor including further CMOS photocells, at least some of which are covered by both a colored filter layer of the first color and a colored filter layer of a second color, stacked one above the other in either order, where the colored filter layer of the second color has a second transmittance that allows light of the other wavelengths to pass. The first sensor produces a first photocurrent, and the second sensor produces a second photocurrent, when light including both the specific and other wavelengths is incident upon the detector. A differential photocurrent, produced by determining a difference between the first and second photocurrents, has a spectral response with at least part of the light of other wavelengths cancelled.

    摘要： A photodetector includes one or more first photodiode regions that are covered by an optical filter configured to reject infrared (IR) light and that produce a first current (I1). The photodetector also includes one or more second photodiode regions that are covered by a light blocking material configured to reject visible and infrared light and that produce a second current (I2). The photodetector also includes one or more third photodiode regions that are not covered by the optical filter and are not covered by the light blocking material and that produce a third current (I3). Additionally, the photodetector includes circuitry configured to produce an output indicative of the first current (I1) or a scaled version of the first current (I1), minus the second current (I2) or a scaled version of the second current (I2), minus the third current (I3) or a scaled version of the third current (I3). The optical filter configured to reject IR light can be, e.g., a dielectric reflective optical coating filter, an IR absorption optical coating filter, or a combination thereof.
