Abstract
A column circuit for single-ended to fully differential conversion includes capacitors for sampling a pixel signal level, and capacitors for sampling a pixel reset level; and switches for connecting capacitors for sampling the pixel signal level and capacitors for sampling the pixel reset level in opposite polarity, thereby realizing symmetrical differential signals on two output nodes. A method is provided for single-ended to fully differential conversion, and a use of the column circuit for single-ended to fully differential conversion.
