US Patent Issued to OMNIVISION TECHNOLOGIES on May 6 for "High dynamic range CMOS image sensor pixel with reduced metal-insulator-metal lateral overflow integration capacitor lag" (California Inventor)

ALEXANDRIA, Va., June 10 -- United States Patent no. 12,294,799, issued on May 6, was assigned to OMNIVISION TECHNOLOGIES INC. (Santa Clara, Calif.).

"High dynamic range CMOS image sensor pixel with reduced metal-insulator-metal lateral overflow integration capacitor lag" was invented by Woon Il Choi (Sunnyvale, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A pixel circuit includes a photodiode configured to photogenerate image charge in response to incident light. A floating diffusion is coupled to receive the image charge from the photodiode. A transfer transistor is coupled between the photodiode and the floating diffusion to transfer the image charge from the photodiode to the floating diffusion....
