Abstract
A system and method of routing multiple pixels from a single column in a CMOS (complementary metal-oxide semiconductor) image sensors (CIS) to a plurality of column analog-to-digital converters (ADCs) is disclosed. The CIS includes an array of pixel elements having a plurality of rows and a plurality of columns. A plurality of column-out signal paths is coupled to each of the plurality of columns of the array of pixel elements. A column routing matrix is coupled to each plurality of column-out signal paths for each of the plurality of columns. A plurality of analog-to-digital converters (ADCs) are coupled to the column routing matrix. The column routing matrix is configured to route at least one column-out signal path to each of the plurality of ADCs during a down-sampling read operation.
