Dear all:
It's me again. Thanks Steve first to provide us good explanation of our =
last question....
We then come out another one that in crosstalk calculation, why the =
trace width does not be counted in..
For example, in Dr. Howard Johnson's first book page 192, there wrote:
Crosstalk ~ K / (1 + (D/H)*(D/H)), where D: distance between two traces =
center to center. H: height above the reference plane
In real application, a pattern of 4.5/15 (trace width 4.5 and space 15) =
will really have larger crosstalk than 5/15? (say the H is 4.1mil)
Best regards!
