Once again, note that Equation 4 clearly shows that the value of the inductance
will change quickly with the loop area, and much more slowly with the conductor size.
The company's new Transpar power transmission module allows testing of high-speed/high-current devices at extraordinarily low inductance
The aforementioned modeling approach requires calculating via capacitance and inductance
Working with Sequence, we developed a new clock analysis methodology taking inductance
into account as well, significantly improving our results and overall quality of the design.
The via inductance
is often more critical (to digital design) than its capacitance.
To keep the switching noise below an acceptable level, keep the mutual inductance
in nH below 2.
The goal in most interconnects associated with the power delivery network is to reduce the loop inductance
of the power-return path as much as possible.
5 nsec, with a 50 [ohm] impedance environment and a total inductance
for the return or ground lead of 2 nH, when any signal line makes up the rest of the loop.
With our solution for large SoC inductance
extraction, we continue our leadership in supplying the most advanced techniques for high complexity, high performance SoC design," said Gerald C.
There is a simple relationship between the total loop inductance
of a line, the time delay of the line and its characteristic impedance:
The 0603E series consists of 20 products covering inductance
values from 2 to 12 nanohenries (nH).
Since the inductance
requirement has an inverse proportionality relationship with switching frequency, high switching frequency means that a very small inductance
can be used.
