Abstract
A method for writing to a pixel, the method includes: activating an input transistor and a second transistor; wherein the second transistor is coupled to a second node and the input 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 to a pixel node that is capacitively coupled to the second node via at least one pixel capacitance; repeating, until a control criterion is fulfilled, the stages of: inactivating the input transistor, and measuring a pixel output signal; and operating the input transistor in a weakly conductive mode and providing to the pixel a feedback signal that is responsive to a result of the measurement of the pixel output signal.
