Abstract :
A CMOS photodetector array with in-pixel electronics has been developed for computed tomography (CT) applications. Consisting of 10/spl times/20 pixel array in-pixel electronics has been designed to achieve 17 bits dynamic range and a quantum limited system under CT operating range. A series of limitations have been overcome to integrate both photodiode and a charge-sensing amplifier at pixel level.
