Recent developments in CMOS image sensors have focused on the advancement of digital pixel sensors (DPS). A novel DPS aiming to combine multiple functionalities on the imaging plane has been designed and tested: The on pixel intelligent CMOS (OPIC) sensor was manufactured in a 0.25 mum logic process with 5 metal layers, and 8 mum epitaxial layers. The sensor comprises three 2 x 2 mm test arrays of 30 mum pixels. Two of the test arrays are named "advanced" and include two 8-bit DRAM cells, one 8… CONTINUE READING
