  • Patent number: 11678079
    Abstract: An object is to improve a frame rate in a solid-state imaging element that employs a global shutter method. In the solid-state imaging element, a photoelectric conversion element generates a charge by photoelectric conversion. A charge holding transistor holds the charge. A backward flow prevention transistor generates a potential barrier between the photoelectric conversion element and the charge holding transistor immediately after the charge is transferred from the photoelectric conversion element to the charge holding transistor. A floating diffusion layer accumulates the charge and generates a voltage corresponding to an amount of the charge. A transfer transistor transfers the charge from the charge holding transistor to the floating diffusion layer.

  • Patent number: 11653119
    Abstract: In a solid-state image sensor provided with a comparator that compares a reference signal and a pixel signal, the image quality of image data is improved. A voltage divider circuit supplies a divided voltage of an input voltage and a predetermined reference voltage that are input. An input-side differential transistor outputs a drain current corresponding to the gate-source voltage between the divided voltage input to the gate and a predetermined source voltage. An output-side differential transistor outputs a voltage corresponding to the drain current as a result of comparison between the input voltage and the reference voltage. A control transistor reduces the gate-source voltage in a case where the input voltage is out of a predetermined range.

  • Patent number: 11647311
    Abstract: An image sensor may include an array of image pixels arranged in rows and columns. The columns of pixels are coupled to corresponding delta sigma modulators. Each group of delta sigma modulators may be coupled to a column memory circuit. The column memory circuit may receive bits serially from each pixel column in the group. Once all bits in a bit stream from each pixel column have been stored into the column memory circuit, the column memory circuit may output one bit stream at a time to a shared filter circuit. The shared filter circuit may process an entire bit stream associated with a given column in one cycle. Sharing the filter circuit among multiple pixel columns can dramatically reduce circuit area for the image sensor.
