Abstract
An image sensor includes a logic die, including column readout circuits and bitlines connected to the column readout circuits. A sensor die is overlaid on the logic die. The image sensor includes an array of detector elements, each including a sensing circuit on the sensor die, which includes a photodiode, a floating diffusion node connected to one of the terminals of the photodiode, a reset transistor coupled to the floating diffusion node, and a source follower transistor. In each detector element, a pixel circuit on the logic die includes a select transistor, which has an input coupled to the output of the source follower and an output coupled to one of the bitlines. A current memory circuit is coupled to the input of the select transistor and is configured to sense and output a signal indicative of a level of noise in the detector element.
