Abstract :
Two 2.5V VGA CMOS image sensors with 3.45μm and 3.1μm buried photodiode-pixels on a 0.25μm 2P3M CMOS technology are described. The test chips utilize a floating diffusion driving technique to achieve 3-transistors/pixel and 2-transistors/pixel respectively, and operate at 60 frames/s with 49mW dissipation.
