Abstract
A device for cancelling undesired fractions in a detected signal may include a first region having an output node and including a light sensitive sensor configured to detect a first signal and an analogue to digital converter coupled to the output node. A second region may be switchably coupled to the first region based on a first control signal to the first region. The second region may include a storage device configured to store a signal based on the detection of the first signal. The second region may include an output node coupled to the sensor. The second may be configured to provide a compensation signal based on the stored signal to the light sensitive sensor during detection of a second signal.
