  • Publication number: 20200244907
    Abstract: It makes it easier to reduce the line capacitance of vertical signal lines in a solid-state image sensor in which signals are output via the vertical signal lines. The solid-state image sensor is provided with a logic circuit, a pixel circuit, and a negative capacitance circuit. In the solid-state image sensor, the logic circuit processes an analog signal. Also, in the solid-state image sensor, the pixel circuit generates an analog signal by photoelectric conversion, and outputs the analog signal to the logic circuit via a predetermined signal line. In the solid-state image sensor, the negative capacitance circuit is connected to the predetermined signal line.
