Abstract:
Apparatuses and methods for charge transfer in image sensors are disclosed. One example of an image sensor pixel may include a first charge storage node and a second charge storage node. A transfer circuit may be coupled between the first and second charge storage nodes, and the transfer circuit may have a first region proximate the first charge storage node and configured to have a first potential. The transfer circuit may also have a second region proximate the second charge storage node configured to have a second, higher potential. An input node may be configured to control the first and second potentials based on a transfer signal provided to the input node.
