Abstract
A light sensor arrangement according to the proposed principle comprises at least one first unshielded well (D) and at least one second shielded well (D) in a substrate (P). The at least one first unshielded well (D) is being exposed to incident light (λ) and configured to generate a first sensor signal (Ch) as a function of the incident light (λ). The at least one second shielded well (D) in the substrate (p) being shielded from the incident light (λ) and configured to generate a second sensor signal (Ch) as a function of the incident light (λ). The light sensor arrangement further comprises means for temperature compensation providing the first and second sensor signals (Ch, Ch) as temperature compensated sensor signals as a function of substrate temperature. Means to determine spectral content of the incident light (λ) are provided to determine the spectral content as a function of the temperature compensated first and second sensor signals (Ch, Ch).
