A stepped-width, co-spiral inductor structure includes a first exterior layer having a first exterior width. The stepped-width, co-spiral inductor structure also includes a first interior layer coupled to the first exterior layer. The first interior layer includes a first interior width that is wider than the first exterior width of the first exterior layer. The stepped-width, co-spiral inductor structure further includes a second exterior layer coupled to the first interior layer. The second exterior layer includes a second exterior width that is narrower than the first interior width of the first interior layer.
