Abstract
A hybrid bonded image sensor has a photodiode die with macrocells having at least one photodiode and a bond contact; a supporting circuitry die with multiple supercells, each supercell having at least one macrocell unit bonded to the bond contact of a macrocell of the photodiode die. Each macrocell unit has a reset transistor adapted to reset photodiodes of the photodiode die macrocell. Each supercell has a differential amplifier configurable to receive a noninverting input from a photodiode and an inverting input, the differential amplifier providing an output, each differential amplifier has an amplifier reset transistor coupled to the differential amplifier output and the inverting input; a first capacitor coupled between the differential amplifier output and the inverting input, and a second capacitor coupled between the inverting input and a signal ground. The first and second capacitor of embodiments has controllable capacitance to adjust gain.
