  • Publication number: 20260190522
    Abstract: Provided is an image-capturing apparatus that can reduce deterioration of the performance. An image-capturing apparatus includes a semiconductor layer, multiple pixels provided on the semiconductor layer, an inter-pixel separating section that is provided on the semiconductor layer and separates one pixel and another pixel that are adjacent to each other in the multiple pixels, and pixel transistors connected to the multiple pixels. The pixel transistors include a first transistor and a second transistor adjacent to the first transistor with the inter-pixel separating section being interposed therebetween. A gate electrode of the first transistor and a gate electrode of the second transistor are integrated via an upper portion of the inter-pixel separating section.

  • Patent number: 11448178
    Abstract: A switch control circuit controls a switch element connected to a primary coil of an ignition coil in accordance with an ignition signal. The switch element includes a transistor and a protection element connected between a collector and gate of the transistor. The switch control circuit uses a voltage at a gate terminal controlling the transistor or a voltage corresponding to a collector current of the transistor as a detection voltage and generates a status detection signal corresponding to a change in the detection voltage.
