  • Publication number: 20230009222
    Abstract: A method for controlling noise on an electronic device may include determining that a measured characteristic, associated with an antenna in a first configuration and included on the electronic device, violates a predetermined threshold. The method may also include identifying an aggressor in a second configuration, which may be a component on the electronic device. The aggressor may emit electromagnetic (EM) radiation that causes the measured characteristic to violate the predetermined threshold. One or more stimuli may be determined based on the first and/or second configurations that would cause the measured characteristic to no longer violate the predetermined threshold. One or more stimuli may be applied to the antenna and/or the aggressor, causing the measured characteristic to no longer violate the predetermined threshold.

  • Publication number: 20220404878
    Abstract: A method and system for applying materials to an electronic device may include generating an electromagnetic (EM) map of the device. The EM map may indicate locations of EM radiation emitted from the electronic device. The method may also include generating a thermal map of the electronic device that may indicate locations of thermal energy emitted from the device. The method may also include generating a shielding map from the EM thermal maps. The shielding map may include instructions to control a shielding apparatus, including locations on the electronic device to apply an EM shielding material and a thermal material. The method may also include controlling a shielding apparatus to apply the EM shielding material and thermal material to the electronic device, according to the shielding map. The EM shielding material and thermal material may be applied to varying depths on the electronic device.

  • Patent number: 8824226
    Abstract: Some embodiments are related to a mesh capacitor, which improves the SER FIT rate. In an embodiment, the capacitor is connected between an input and an output of a latch in a flip-flop, making the flip-flop harder to flip due to radiation (e.g., from neutrons and/or alpha particles). In some embodiments, the capacitor is built directly vertically on top of the flip-flop, saving chip layout areas.
