Abstract

A signal conditioning circuit for a light sensor, in particular for an ambient light sensor, comprises a first integration stage (INT) connected to a first sensor input (IN) to receive a first and second sensor signal and a second integration stage (INT) comprising a coupling input (IN) to receive from the first integration stage (INT) a first and second integrated sensor signal. A coupling stage (S, C) is connecting the first and second integration stages (INT, INT) 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.
