Hi,
I have two Aluminum lines (Line1 and Line2) of width W spaced by S. There
is no third metal.
Assume, the single ended characteristic impedance of Line1 is Z0.
Now, if I excite Line1 and Line2 differentially, will the differential
impedance also be Z0?
Below is my explanation. Can any of the experts provide feedback on the
given scenario and correct me if I am wrong?
*My explanation:*
In both single ended and differential excitation, the voltage and current
is between Line1 and Line2. So when differential voltage is considered,
current also doubles. Therefore the differential impedance and single ended
impedance are the same.
