Patent ID: 8077236

Claim:
An imaging device, comprising: a pixel array having a plurality of pixels arranged in rows and columns, at least one pixel of the array comprising: a photosensor; a first reset transistor operable to reset the photosensor, wherein the first reset transistor has a first source-drain terminal, a second source-drain terminal, and a gate terminal and wherein the first source-drain terminal of the first reset transistor is coupled to the photosensor; a global reset line, wherein the gate terminal and the second source-drain terminal of the first reset transistor are coupled to the global reset line; a first storage node including a floating diffusion region operable to store charges generated by the photosensor; a second storage node operable to store the charges generated by the photosensor; a first transfer transistor operable to transfer the charges generated by the photosensor from the photosensor to the second storage node; a second transfer transistor operable to transfer the charges generated by the photosensor from the second storage node to the floating diffusion region of the first storage node; and a second reset transistor operable to reset the floating diffusion region of the first storage node, wherein the second reset transistor has a first source-drain terminal, a second source-drain terminal, and a gate terminal, wherein the first source-drain terminal of the second reset transistor is coupled to the floating diffusion region of the first storage node, wherein the gate terminal and the second source-drain terminal of the second reset transistor are coupled to a column line.
