  • Publication number: 20160254236
    Abstract: Ground shielding is achieved by a conductor shield having conductive surfaces that immediately surround individual chips within a multichip module or device, such as a multichip module or device with flip-chip (FC) bumps. Intra-module shielding between individual chips within the multichip module or device is achieved by electromagnetic or radio-signal (RF) isolation provided by the surfaces of the conductor shield immediately surrounding each of the chips. The conductor shield is directly connected to one or more grounded conductor portions of a substrate or interposer to ensure reliable grounding.

  • Publication number: 20160181233
    Abstract: Metal-insulator-metal (MIM) capacitors arranged in a pattern to reduce inductance, and related methods, are disclosed. In one aspect, circuits are provided that employ MIM capacitors coupled in series. The MIM capacitors are arranged in a pattern, wherein a MIM capacitor is placed so as to be electromagnetically adjacent to at least two MIM capacitors, and so that a current of the MIM capacitor flows in a direction opposite or substantially opposite of a direction in which a current of each adjacent MIM capacitor flows. The magnetic field generated at metal connections of each MIM capacitor rotates in an opposite direction of the magnetic field of each electromagnetically adjacent MIM capacitor, and thus a larger proportion of magnetic fields cancel out one another rather than combining, reducing equivalent series inductance (ESL) compared to linear arrangement of MIMs.

  • Patent number: 9335384
    Abstract: A method and apparatus for testing near field magnetic fields of electronic devices. The method comprises measuring a magnetic field using a loop antenna that is oriented in a first direction. The loop antenna is swept through a desired range of azimuth angles while measuring the magnetic field. Once the first direction testing is completed, the loop antenna is changed to a second orientation direction. The magnetic field is then measured in the second orientation direction and is swept through a desired range of orientation angles in the second direction. The apparatus provides a loop antenna connected to a coaxial probe, with the coaxial cable serving as the center conductor, and two outer conductors. An axle is mounted to the loop antenna and connected to a step motor. A servo motor is also provided for moving the arm assembly.
