摘要： An imager in which a column line bias current control signal is pulsed at some time during and/or after the pulsing of the reset control and the transfer control signals to increase a bias current in a pixel column line during reset and transfer operations. The bias current is then decreased by removing the pulse before the sampling and storing of reset and image signals. Pulsing the bias control voltage signal and thus, the bias current, decreases the settling time of the column line, while maintaining the required low current during sampling and storage of the reset and image signals.
摘要翻译：在复位控制和传输控制信号的脉冲期间和/或之后的某个时间，列线偏置电流控制信号被脉冲的成像器，以在复位和传送操作期间增加像素列线中的偏置电流。然后通过在采样和存储复位和图像信号之前去除脉冲来减小偏置电流。脉冲偏置控制电压信号，从而偏置电流降低了列线的建立时间，同时在采样和存储复位和图像信号期间保持所需的低电流。

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.

摘要： A pixel having a well-isolated charge storage region or floating diffusion region may be obtained by providing a separate P-well around the storage region or floating diffusion region. In one embodiment, a separate P-well entirely encases the storage region and is in contact with the storage region. This P-well provides an electrical barrier for preventing electrons that are generated elsewhere in the pixel from contaminating the storage region. In another embodiment, a first separate P-well encases and is in contact with the storage region and a second separate P-well encases and is in contact with the floating diffusion region.

摘要： A method of operating an imager pixel that includes the act of applying a relatively small voltage on the gate of a transfer transistor during a charge acquisition period. If a small positive voltage is applied, a depletion region is created under the transfer transistor gate, which creates a path for dark current electrons to be transferred to a pixel floating diffusion region. The dark electrons are subsequently removed by a pixel reset operation. If a small negative voltage is applied to the transfer gate, electrons that would normally create dark current problems will instead recombine with holes thereby substantially reducing dark current.
