  • Patent number: 11375145
    Abstract: In a solid-state imaging device 10, a signal retaining part 212 is provided with a first sampling part 2122 and a second sampling part 2123, each of which is formed by one sampling transistor (1T) and one sampling capacitor (1C). The coupling node between the two sampling parts is a retaining node ND23, which is used as a bidirectional port. With such a configuration, the solid-state imaging device 10 is configured as a solid-state imaging element having a global shutter function that achieves substantially the same signal amplitude as in the differential reading scheme with four transistors. Thus, the solid-state imaging device 10 can achieve the reduced increase in number of transistors, prevent the occurrence of signal amplitude loss in the sampling parts, maintain high pixel sensitivity and reduce input conversion noise.
