  • Abstract
    A pixel-level ADC technique for CMOS image sensors is presented. As the charge represents accurately the amount of illumination, the principle consists in counting small charge packets which come from the detector. Based on a 0.13 mum CMOS technology, simulation results and first measurements are presented showing that the LSB value can be reduced to 1900 electrons with a static power of 250 nW per pixel. For the moment, due to the available technology, this technique, is restricted to medium size pixels, i.e. 50x50 mum2.
