Latest Patents
Chinnaveerappan's latest patents include a "Method and apparatus for shielding correction pixels from spurious charges in an imager." This invention introduces a barrier designed to isolate dark correction pixels from unwanted charges within an image sensor. The barrier features a charge absorbing region in a substrate that is electrically connected to a voltage source terminal. This region surrounds the dark correction area of a pixel array, effectively absorbing carriers generated by lateral diffusion, near-infrared, and infrared light reflected from the silicon substrate. This innovation prevents distortion in image correction caused by unwanted carrier absorption.
Another notable patent is for "Methods and apparatuses for pixel testing." This invention provides methods for non-optical testing of imaging devices that contain an array of pixels. The testing process involves setting the photoconversion device and/or a floating diffusion region to a known voltage level, which differs from the operational voltage during non-test conditions. The pixel is then sampled and compared to an expected value, ensuring accurate performance assessment.
