Abstract:
An optical sensor arrangement comprises a photodiode (11) and an analog-to-digital converter (12). The analog-to-digital converter (12) comprises an integrator (13) having an integrator input (15) coupled to the photodiode (11), a comparator (14) having a first input coupled to an output of the integrator (13) and a digital-to-analog converter (39) coupled to a control terminal of the comparator (14).
