  • Data processing systems having mismatched impedance components
    Patent number: 6788073
    Abstract: A data processing system having mismatched impedance components and method of use is disclosed. In one embodiment, the method includes exciting a printed circuit board circuit having mismatched impedance printed circuit board components. Measuring at least one impedance of the circuit with a time domain reflectometer. In response to the measured at least one impedance of the circuit, adjusting at least one printed circuit board circuit element.
    Type: Grant
    Filed: September 6, 2002
    Date of Patent: September 7, 2004
    Assignee: Dell Products L.P.
    Inventors: Douglas E. Wallace, Steven J. Lash, Stephanus D. Saputro
  • Reducing inductance of a capacitor
    Patent number: 6762368
    Abstract: The inductance of the capacitor is reduced by connecting the capacitor directly to a via. In one embodiment inductance of a capacitor is reduced by a plurality of via, the number of via greater than the number of electrical couplings from the voltage pad to the voltage plane. In one embodiment the capacitor has a ground pad of a minimum size. In another embodiment the capacitor is electrically coupled to a trace having a length reduced to minimize inductance.
