Abstract: A light sensor arrangement according to the proposed principle comprises at least one first unshielded well (D0) and at least one second shielded well (D1) in a substrate (P). The at least one first unshielded well (D0) is being exposed to incident light (λ) and configured to generate a first sensor signal (Ch0) as a function of the incident light (λ). The at least one second shielded well (D1) in the substrate (p) being shielded from the incident light (λ) and configured to generate a second sensor signal (Ch1) 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 (Ch0, Ch1) 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 (Ch0, Ch1).

Abstract: A signal conditioning circuit for a light sensor, in particular for an ambient light sensor, comprises a first integration stage (INT1) connected to a first sensor input (IN1) to receive a first and second sensor signal and a second integration stage (INT2) comprising a coupling input (IN2) to receive from the first integration stage (INT1) a first and second integrated sensor signal. A coupling stage (S3, C5) is connecting the first and second integration stages (INT1, INT2) and is designed to generate a difference signal from consecutively received integrated first and second integrated sensor signals. A sensor arrangement and a method for signal conditioning for a light sensor is also presented.
