Abstract
An array-based C-MOS sensor device is provided with a facility for on the basis of non-destructive cell readout generating a radiation dose-sensing signal. In particular, the facility is arranged for accessing a subset of multiple distributed C-MOS cells across the array and feeding by such accessed cells an algorithmic means for therein generating an overall feedback dose control signalization and/or an over-all trigger signalization.
