Abstract
Methods for reading a pixel and writing to a pixel and devices having pixel reading capabilities and pixel writing capabilities. A method for reading a pixel includes: activating a second transistor that is coupled to a second node while maintaining an input transistor inactive; wherein the first transistor is coupled between the second node and a photo-detector; inactivating the second transistor; compensating for second node voltage change resulting from the inactivating of the second transistor by providing a feedback signal via at least one capacitance that capacitively couples the pixel node to the second node; and activating the input transistor and measuring a pixel output signal.
