Abstract
A transformer includes a first loops and second loops. The first loops include a first set of input terminals. The first loops include at least three loops that are conductively coupled to each other in series by first crossovers. The second loops include a first set of output terminals. The second loops include at least three loops that are conductively coupled to each other in series by second crossovers. Each of the second conductive loops is inductively coupled to and nested within a respective one of the first conductive loops.
Claims22
A transformer comprising:
- a first plurality of loops comprising a first set of input terminals, wherein the first plurality of loops include at least three loops that are conductively coupled to each other in series by first crossovers;
- and a second plurality of loops comprising a first set of output terminals, wherein the second plurality of loops include at least three loops that are conductively coupled to each other in series by second crossovers, wherein each of the second plurality of loops is inductively coupled to and nested within a respective one of the first plurality of loops and is not nested in the other ones of the first plurality of loops, and third crossovers, wherein the first crossovers include a pair of conductors, and wherein the pair of conductors cross each other to connect to two of the first plurality of loops, the pair of conductors connect to a first loop and a second loop;
- the third crossovers comprise a second pair of conductors;
- and the second pair of conductors cross each other and connect to the second loop and a third loop.
A transformer circuit comprising:
- a first transformer comprising a first winding having a first loop, and a second winding having a second loop, wherein the second loop is nested within the first loop;
- and a second transformer nested within the first transformer, wherein the second transformer comprises a third winding having a figure eight structure, and a fourth winding having a figure eight structure, wherein loops of the fourth winding are nested within respective loops of the third winding, and wherein three loops of the third winding are not concentric with each other or three of the loops of the fourth winding are not concentric with each other and the loops of the third winding and the loops of the fourth winding are nested completely within the first transformer.
