ABSTRACT:
An array of multicolor CMOS pixel sensors has a plurality of photosensors per pixel, each photosensor coupled to a single sense node through a select transistor having a select input, each pixel sensor including a reset transistor coupled to the sense node and having a reset input, an amplifier coupled to the sense node and a row-select transistor coupled to the amplifier. The select inputs and the reset inputs for pixel sensors in a pair of adjacent rows are coupled to select signal lines and reset signal lines associated with the pair of rows. The amplifier transistors in individual columns of each row are coupled to a column output line through a row-select transistor having a row-select input. The row-select inputs for pixel sensors in each row of the array are coupled to a row-select line associated with the row.
