Hi All, Would you like to measure risetimes of internal signals on an IC in a package? Something like this is possible using E-field coupling.
Most of my articles on noise touch on magnetic field coupling, but this month's Technical Tidbit presents a simple method of measuring E-field coupled IC chip noise. Such a measurement can be a useful troubleshooting tool for designers and EMC personnel as well. One can even see internal risetimes on the chip. Abstract: Measuring noise coupled onto a copper foil patch applied to a chip package can yield useful data. A method of measurement is suggested and data presented. The data from such a measurement can be useful for design troubleshooting as well as EMC work. Uses related to reliable system operation and as well as conclusions for EMC compliance are presented. As usual, the link to the article is the picture of the experimental setup at the bottom of the homepage at http://emcesd.com. Have a good month, Doug -- ___ _ Doug Smith \ / ) P.O.
