Abstract
An image sensor pixel may include a photodiode, one or more storage diodes, one or more potential barrier structures, one or more capacitors, and a floating diffusion region. The photodiode may be coupled to a storage diode and a first capacitor, and a first potential barrier structure may be interposed between the storage diode and the first capacitor. The photodiode may also be coupled to additional storage diodes and additional capacitors in a similar manner. Additionally, the photodiode may be directly separated from a given capacitor via a corresponding potential barrier structure. Each capacitor may store overflow charge from one or more storage diodes and/or the photodiode and may be connected to the floating diffusion via respective transistors.
