  • Publication number: 20190334514
    Abstract: A high-speed low-power-consumption dynamic comparator includes a latch, an AND gate, a delay unit, and an XNOR gate. According to the high-speed low-power-consumption dynamic comparator, the output signal is generated through the XNOR gate from the comparator output signals Dp and Dn. The output signal and the control signal clk1 generate the control signal of the NMOS transistor P10 through the AND gate, so that the problem of static power consumption in a conventional comparator is solved.

  • Publication number: 20190190257
    Abstract: The present invention provides a chip ESD protection circuit, includes an integrated circuit layer and a conductive layer. A first ground bonding pad that is connected to a first ground wire of a first power domain is disposed on each of the first power domain and a second power domain in the integrated circuit layer. The first ground bonding pads are bonded to the conductive layer. A second power clamping unit is disposed on the second power domain. A first end of the second power clamping unit is connected to a second power wire of the second power domain, and a second end thereof is connected to the first ground wire or a second ground wire of the second power domain. According to the chip ESD protection circuit, the ESD protection capability of a chip can be improved. The occupied area of the chip is reduced.

  • Patent number: 10242120
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for selecting a template for a content item. In one aspect, a method includes receiving a content item request that includes context data. A content item that is eligible to be presented in response to the content item request is identified. A determination is made that the content item includes a template variable that is resolved based on the context data. A template feed including a set of templates is identified based on the template variable. A template is selected from the template feed for the content item. The template can be selected based on the context data. The selected template is populated with content for the content item to create a formatted content item. The formatted content item is provided in response to the content item request.
