US Patent 11069282 Correlated double sampling pixel sensing front end

A system and method for operating a sensing circuit for sensing a pixel current of a pixel of a display panel using correlated double sampling. In some embodiments, the method includes: during a first interval of time, resetting a pixel sensing circuit; during a third interval of time following the first interval of time, operating the pixel sensing circuit in an integration mode; during a fourth interval of time following the third interval of time, operating the pixel sensing circuit in a hold mode; and during a fifth interval of time following the fourth interval of time, operating the pixel sensing circuit in the integration mode.
