Abstract
An image sensor includes a logic die, including column readout circuits, and a sensor die, overlaid on the logic die and including bitlines connected to the column readout circuits and an array of detector elements. Each detector element includes a photodiode having cathode and anode terminals and a floating diffusion node connected to one of the terminals of the photodiode. A first reset transistor is coupled between the floating diffusion node and a reset voltage. A source follower transistor has an input connected to the floating diffusion node and an output connect to a first terminal of an output capacitor having first and second terminals, with the first terminal. A second reset transistor is coupled between a second terminal of the output capacitor and the reset voltage. A select transistor is coupled between the second terminal of the output capacitor and one of the bitlines.
