Abstract
An optical sensor includes an array of pixels, wherein each pixel includes a photodiode configured to receive an optical signal and a floating node coupled to the photodiode. At least one sensing path is capacitively coupled to the floating node of at least one of the pixels. An evaluation unit is coupled to the at least one sensing path to generate an electrical signal dependent on the optical signal received by the photodiode.
