Post subject: Modeling Printed Circuit Board Parasitic Capacitances
Posted: Tue Oct 25, 2005 11:51 am
Good day. When I have simulated
circuits I always had to add the parasitic capacitances (from the printed
circuit board) manually to my simulation. This got to be a very time
consuming process particularily if the circuit was large. I am looking
for some information (book, magazine, website, personal experience,
etc.) about how to determine the parasitic capacitance.
When
I have done a literature search, most of the articles that I find discuss
building test boards and measuring the components, then extracting the
parasitics. I do not want to use this method because it is time consuming.
Also the models are only valid for one type of circuit board (i.e. one
substrate thickness and one dielectric constant, etc.)
Thank
you for your time and help.
Michael
