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.
