## Abstract

The technique of current splitting is presented as part of an integrated circuit development for an X-ray imager. This method enables integration of charge signals of unprecedented magnitude in small pixels, achieving a dynamic range of ${10^5}$. Results from two front end prototypes are given and a final optimized design is proposed.
