    • An image sensor includes a photoelectric converter, a source-follower transistor, and a selection transistor. The photoelectric converter generates electric charge in response to received light, and the electric charge varies a voltage of a detection node. The source-follower transistor is coupled between the detection node and an output node and has a first threshold voltage. The selection transistor is coupled between the source-follower transistor and a voltage node with a power supply voltage or a boosted voltage applied thereon, and has a second threshold voltage with a magnitude that is less than a magnitude of the first threshold voltage such that the source-follower transistor operates in saturation.
    • 图像传感器包括光电转换器,源极跟随器晶体管和选择晶体管。 光电转换器响应于接收到的光而产生电荷,电荷改变检测节点的电压。 源极 - 跟随器晶体管耦合在检测节点和输出节点之间并且具有第一阈值电压。 选择晶体管被耦合在源极跟随器晶体管和具有施加在其上的电源电压或升压电压的电压节点之间,并且具有小于第一阈值电压的幅度的幅度的第二阈值电压,使得 源极跟随器晶体管工作在饱和状态。
