    • A sensing device includes a pixel unit and an output unit. The pixel unit includes a sensing element, a transfer transistor, a reset transistor, and an output transistor. The transfer transistor is coupled between the sensing element and a floating diffusion node. The reset transistor is coupled between a first node and the floating diffusion node. The output transistor has a control terminal coupled to the floating diffusion node and an input terminal coupled to the first node. During a readout period, the reset transistor is controlled by a reset phase to reset a level of the floating diffusion node. The output unit generates a pixel output signal at the first node according to the level of the floating diffusion node and a reference signal. During the readout period, the reference signal is at a higher level, and after the reset phase, the reference signal is at a lower level.
    • 感测装置包括像素单元和输出单元。 像素单元包括感测元件,传输晶体管,复位晶体管和输出晶体管。 传输晶体管耦合在感测元件和浮动扩散节点之间。 复位晶体管耦合在第一节点和浮动扩散节点之间。 输出晶体管具有耦合到浮动扩散节点的控制端和耦合到第一节点的输入端。 在读出期间,复位晶体管由复位阶段来控制,以复位浮动扩散节点的电平。 输出单元根据浮动扩散节点的电平和参考信号在第一节点产生像素输出信号。 在读出期间,参考信号处于较高电平,在复位阶段之后,参考信号处于较低电平。

    • A sensing pixel array is provided and includes a plurality of pixels disposed in an array. Each pixel operates during an exposure period and a readout period and generates a readout signal. Each pixel includes a sensing unit and a sampling unit. The sensing unit senses light to generate a sensing signal during the exposure period. The sampling unit samples the sensing signal to generate a sensing output signal which serves as the readout signal during the readout period. During the exposure period, the sampling unit acts as a memory unit for storing an input signal and outputting an accessed output signal which serves as the readout signal.
    • 提供感测像素阵列并且包括以阵列布置的多个像素。 每个像素在曝光期间和读出期间进行动作,生成读出信号。 每个像素包括感测单元和采样单元。 感测单元在曝光期间感测光以产生感测信号。 采样单元对感测信号进行采样以产生在读出期间用作读出信号的感测输出信号。 在曝光期间,采样单元用作存储单元,用于存储输入信号并输出​​用作读出信号的存取的输出信号。

    • A pipelined recycling analog-to-digital converter (ADC), which converts a first analog input signal into a first digital output signal, including a first conversion stage and a second conversion stage is disclosed. The first conversion stage includes a first processing unit and a second processing unit. The first and the second processing units execute a number of conversion operations. For each conversion operation, an analog value and a digital code are generated by the first or the second processing unit. The first and the second processing units share an operational amplifier, and for each conversion operation. The second conversion stage includes a comparing unit which determines a specific analog value among the analog values generated by the first and the second processing units. When the specific analog value is not located within a predetermined range, the comparing unit generates a reset pulse to reset the operational amplifier.
    • 公开了一种流水线再循环模数转换器(ADC),其将第一模拟输入信号转换为包括第一转换级和第二转换级的第一数字输出信号。 第一转换级包括第一处理单元和第二处理单元。 第一和第二处理单元执行多个转换操作。 对于每个转换操作,由第一或第二处理单元生成模拟值和数字代码。 第一和第二处理单元共享运算放大器,并且用于每个转换操作。 第二转换级包括比较单元,其确定由第一处理单元和第二处理单元生成的模拟值之间的特定模拟值。 当特定模拟值不在预定范围内时,比较单元产生复位脉冲以复位运算放大器。
