Abstract
An inter-wound spiral center tapped inductor includes a first and second spiral inductor trace arranged in a plane in an inter-nested pattern with a center tap connection. The inter-wound traces implement the two halves of a center-tapped inductor over a common area to provide a practical inductor element for use in balanced and differential circuits.
Claims14
An inductor comprising:
- a mounting structure having means for mounting a conductor in a plane;
- a first conductor, mounted in said plane by said means for mounting a conductor, extending from a first terminal to a second terminal and arranged in said plane in a first spiral pattern, said first spiral pattern having spiral loops;
- a second conductor, mounted coplanar with said first conductor in said plane by said means for mounting a conductor, extending from a third terminal to a fourth terminal and arranged in said plane according to a second spiral pattern, said second spiral pattern having spiral loops and being substantially identical to said first spiral pattern and located so that at least one of the spiral loops of said second conductor extends between the spiral loops of said first spiral pattern;
- and
- a centertap having means for connecting said second terminal to said fourth terminal.

A centertap inductor comprising:
- a first spiral conductor and a second spiral conductor, said first and second spiral conductors arranged in a common plane on a mounting surface and arranged in a mutually nested spiral pattern;
- a center connect terminal connected to a first end of each of said first and second spiral conductors;
- a first terminal connected to a second end of said first spiral conductor;
- and
- a second terminal connected to a second end of said second spiral conductor.
