Abstract: Disclosed herein are electronic devices and image sensors containing pixel arrays, layouts of electrical signal lines for such pixel arrays, and methods of pixel read out operations, including row read operations, for such pixel arrays. Layouts are disclosed that have reduced sets of shielding or ground lines. In some layouts, shielding ground lines are used only between pairs of adjacent pixel output signal lines (OSLs). Also disclosed is a method of using one OSL within a pair of adjacent pixel OSLs to provide settling assist of the pixel output signal on the other OSL of the adjacent pair of OSLs.

Abstract: A camera may one or more lenses and an image sensor having an array of light-gathering pixels. The pixels may generate image signals based on light passing through the lenses. The camera may include at least one pixel output settling assist circuit. The pixel output settling assist circuit may be electrically coupled to an output signal line of at least one of the pixels. The pixel output settling assist circuit may include a pixel output voltage change detection circuit and a bias current adjustment circuit. During read-out of the image signals of the at least one pixel, the pixel output voltage change detection circuit may detect a change of a voltage at the output of the pixel. The bias current adjustment circuit may generate and adjust a current injected to the output based on the detected change of the voltage at the output.
