Integrated circuits and methods of producing the same are provided. In an exemplary embodiment, an integrated circuit includes a photodetector, where the photodetector includes an impingement photodetector well and a base photodetector well. A transfer transistor overlies the photodetector, where the transfer transistor includes a transfer gate, a source, and a drain. A source contact is electrically connected to the source, and the source contact is also electrically connected to the photodetector.
