Abstract
An imaging device includes a pixel array of 1×3 pixel circuits that include 3 photodiodes in a column. Bitlines are coupled to the 1×3 pixel circuits. The bitlines are divided into groupings of 3 bitlines per column of the 1×3 pixel circuits. Each column of the 1×3 pixel circuits includes a plurality of first banks coupled to a first bitline, a plurality of second banks coupled to a second bitline, and a plurality of third banks coupled to a third bitline of a respective grouping of the 3 bitlines. The 1×3 pixel circuits are arranged into groupings of 3 1×3 pixel circuits per nine cell pixel structures that form a plurality of 3×3 pixel structures of the pixel array.
