Abstract
An optical sensor arrangement () comprises a light sensor () that is connected to a summation node () and is designed for generating a sensor current (S), a current source (S) connected to the summation node () and designed to provide a source current (S), and an integrator () that is coupled to the summation node () and is designed for generating a first value (VP) of an integrator signal (S) by integrating during a first phase (P) and for generating a second value (VP) of the integrator signal (S) by integrating during a second phase (P). The optical sensor arrangement () comprises a sum and hold circuit () that is coupled to the integrator () and is designed to generate an analog output signal (S) as a function of a difference of the first value (VP) and the second value (VP) of the integrator signal (S).
