The transformer comprises first loops and second loops. The first loops comprise a first set of input terminals. The first loops include at least three loops conductively coupled to each other in series by first crossovers. The second loops comprise a first set of output terminals. The second loops include at least three loops conductively coupled to each other in series by second crossovers. Each of the second conductive loops is inductively coupled to and enclosed with each first conductive loop of the first conductive loops.
