Abstract:
This is generally directed to systems and methods for reduced metal lines and control signals in an imaging system. For example, in some embodiments a pixel cell of an imaging system can operate without a row select transistor, and therefore can operate without a row select metal control line. As another example, in some embodiments a pixel cell can share its reset transistor control line with a transfer transistor control line of another pixel cell. In this manner, an imaging system can be created that averages a single metal line per pixel cell. In some embodiments, operation of such reduced-metal line imaging systems can use modified timing schemes of control signals.
