    • An image sensor includes a pixel array, a bit line, supplemental capacitance node line, and a supplemental capacitance circuit. The pixel array includes a plurality of pixel cells each including a floating diffusion (“FD”) node and a photosensitive element coupled to selectively transfer image charge to the FD node. The bit line is coupled to selectively conduct image data output from a first group of the pixel cells. The supplemental capacitance node line is coupled to the FD node of a second group of the pixel cells to selectively couple a supplemental capacitance to the FD nodes of the second group in response to a control signal. In various embodiments, the first and second group of pixel cells may be the same group or a different group of the pixel cells and may add a capacitive boost feature or a multi conversion gain feature.
    • 图像传感器包括像素阵列,位线,补充电容节点线和补充电容电路。 像素阵列包括多个像素单元,每个像素单元包括浮动扩散(FD)节点和耦合以选择性地将图像电荷传送到FD节点的感光元件。 位线被耦合以选择性地进行从第一组像素单元输出的图像数据。 辅助电容节点线耦合到第二组像素单元的FD节点,以响应于控制信号选择性地将辅助电容耦合到第二组的FD节点。 在各种实施例中,第一和第二组像素单元可以是相同的组或像素单元的不同组,并且可以添加电容性升压特征或多转换增益特征。
