Patent ID: 7745773

Claim:
An array of CMOS pixel sensors, each pixel sensor associated with a row and a column of the array and having a plurality of photosensors per pixel location, 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 transistor coupled to the sense node and a row-select transistor coupled to the amplifier, wherein: the select inputs for pixel sensors in a pair of adjacent rows are coupled to select signal lines associated with only that pair of rows; the reset inputs for pixel sensors in each row is coupled to reset signal lines associated with that row; 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; and the row-select inputs for pixel sensors in each row of the array are coupled to a row-select line associated with the row.
