Patent number: 10998121Abstract: An inductor coil includes a wire which is wound in alternating layers such that the surface area of the wire in each winding viewed from above or below the coil is substantially equal in each half of the coil defined by a line bisecting the center point in each layer. The layers are also wound in a serpentine fashion to balance the capacitance between layers. The substantially equal surface area of wire in each half of a coil layer and in adjacent coil layers results in a balanced capacitance of the coil which, in turn, results in reduced common mode noise.Type: GrantFiled: July 31, 2017Date of Patent: May 4, 2021Assignee: Apple Inc.Inventors: Yehonatan Perez, Makiko K.
