Hi Si Gurus I was wondering that is the inductance of PCB trace over a ground plane. Is inductance changes logarithmic with width or is inversely proportionally. These sites shows formulas which say loghttp://www.informit.com/articles/article.aspx?p9477&seqNum=9 http://www.daycounter.com/Calculators/Microstrip-Inductor-Calculator.phtml whereas this says inversely http://www.technick.net/public/code/cp_dpage.php?aiocp_dp=util_inductance_trace_g . May be they take different assumption? what can somebody explain to me what is the assumption?Book i am reading shows derivation of this formula assuming distance from plane is much less than width of the trace which is simmillar to assumption mentioned in link with formula with log version.
