Optical sensor arrangement and method for light sensing

Optical sensor arrangement and method for light sensing

An optical sensor arrangement (10) comprises a photodiode (11) for providing a sensor current (IPD) and an analog-to-digital converter arrangement (12) which is coupled to the photodiode (11) and determines a digital value of the sensor current (IPD) in a charge balancing operation in a first phase...

Zusammenfassung:An optical sensor arrangement (10) comprises a photodiode (11) for providing a sensor current (IPD) and an analog-to-digital converter arrangement (12) which is coupled to the photodiode (11) and determines a digital value of the sensor current (IPD) in a charge balancing operation in a first phase (A) and in another conversion operation in a second phase (B).
