    摘要： 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.

    摘要： Methods and apparatuses for reducing dark current and hot pixels in CMOS image sensors. A pixel apparatus includes a photosensor capable of generating dark current, a floating diffusion region coupled to the photosensor by way of a charge transfer transistor, a rest transistor connected between the floating diffusion region and an array pixel supply voltage. The array supply voltage varies between first and second voltages when sampling pixel signals from the pixel.

    摘要： A method and apparatus are provided for operation of an image sensor during signal readout. During a reset operation the gate of a reset transistor coupled to the storage node receives a voltage greater than a threshold voltage to produce a reset of the storage node. During a period where photogenerated charges stored at the storage node are read out the gate of the reset transistor receives a voltage VRST—LOW greater than ground, but less than a maximum voltage which can be stored at the storage node.
