ABSTRACT:
Imaging devices—as well as methods for operating such devices—that include active pixel sensors and a transistor that, when paired with the transistor in an adjacent pixel, will form a differential input pair of an operational amplifier. At least some portion of the operational amplifier circuit is located off the active pixel sensor, and shared by the rows or columns of the active pixel sensor array.
