An integrated transformer can be fabricated to include multiple first conductors, a magnetic core, and multiple second conductors. The first conductor can be fabricated within a first layer of a semiconductor layer stack. The magnetic core can be fabricated within multiple second layers, below the first layer, of the semiconductor layer stack. The multiple second conductors can be fabricated within a third layer, below the second layer, of the semiconductor layer stack. The multiple first conductors can be connected to the multiple second conductors to form a primary winding of the integrated transformer. The integrated transformer can additionally include a coupling element to wrap around the magnetic core to form a secondary winding of the integrated transformer.

The disclosure provides an inductor and a method for producing the same. The inductor includes a first core made of a first magnetic material; at least two windings, configured to be twisted with each other and embedded within the first core, each winding having a pair of terminals extending out of the first core.

A coil component includes an annular core and a first coil and a second coil wound around the core. The first coil and the second coil include first wire members and second wire members.
