The Center Tapped Topology is one of the two models available for the Inductor Model Extractor. The other is the Untapped Topology.

The Center Tapped model is appropriate under the following conditions:

• The inductor should have 3 or more ports.

• Ports 1 and 2 are input ports.

• Port 3 is the center tap.  

• All other ports are shorted to the box.

• The analysis frequency band should extend from the frequency where Q exceeds unity to where the inductor achieves self resonance.
