    • A solid-state imaging device that outputs a pixel signal having a signal level corresponding to charges generated by a photoelectric conversion includes a comparator. The comparator has a first amplifying unit with first and second transistors configured as a differential pair and provides a signal output by amplifying a difference of signals input to the gate electrodes of the first and second transistors. It also has a second amplifying unit that amplifies the signal output, a first condenser disposed between the gate electrode of the first transistor and a reference signal supply, a second condenser disposed between the gate electrode of the second transistor and pixel signal wiring that reads out the pixel signal, and a switching circuit that connects the reference signal supply to the pixel signal wiring.
    • 输出具有与由光电转换产生的电荷相对应的信号电平的像素信号的固态成像装置包括比较器。 比较器具有第一放大单元,其中第一和第二晶体管被配置为差分对,并且通过放大输入到第一和第二晶体管的栅电极的信号的差来提供信号输出。 它还具有放大信号输出的第二放大单元,设置在第一晶体管的栅电极和参考信号电源之间的第一电容器,设置在第二晶体管的栅电极和读出第二晶体管的像素信号布线之间的第二电容器 像素信号,以及将参考信号电源连接到像素信号布线的开关电路。
