Dear Jongbae, Interesting question. You may want to look at the book "Power Integrity Modeling and Design for Semiconductors and Systems", Prentice Hall, Dec 2007 http://www.amazon.com/Integrity-Modeling-Semiconductors-Prentice-Semiconductor/dp/0136152066 There is a section in Ch2 on Field Penetration through Planes. This section has theory and measurements that may answer your question. Best Regards, Madhavan > Hi, all > Assuming there is a significant high frequency power/ground noise inside a > power/ground plane pair, which size is infinite, (Plane is thick enough) > when we probe (for measurement) the power/ground noise at the inner side > of power/ground plane, we can observe the power/gound noise waveform > generated inside the plane pair. > How do you think if we probe the power/ground noise at the outer side of > power/ground plane? Can we still get the same waveform? or we cannot > oberve > any voltage because of skin effect? > I think we can have almost same waveform because, even if there is no any > current at the outer side of power/ground plane due to skin effect, the > noise potential is still effective at the outer side of planes. am i > wrong? > > Please give me your advice. > > Thanks in advance, > Jongbae. > > > ------------------------------------------------------------------ > To unsubscribe from si-list: > si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field > > or to administer your membership from a web page, go to: > //www.freelists.org/webpage/si-list > > For help: > si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field > > > List technical documents are available at: > http://www.si-list.net > > List archives are viewable at: > //www.freelists.org/archives/si-list > or at our remote archives: > http://groups.yahoo.com/group/si-list/messages > Old (prior to June 6, 2001) list archives are viewable at: > http://www.qsl.net/wb6tpu > > > -- Madhavan Swaminathan Joseph M.
