Patent ID: 8754736

Claim:
An inductor structure comprising: a base material; at least one bottom spiral conductor disposed on the base material, the at least one bottom spiral conductor having a plurality of turns; a middle spiral conductor disposed on the bottom spiral conductor, the middle spiral conductor having a plurality of turns; a top spiral conductor disposed on the middle spiral conductor, the top spiral conductor having a plurality of turns; and dielectric material separating the bottom, middle and top spiral conductors; wherein the at least one bottom spiral conductor is connected electrically in parallel to the middle spiral conductor and the middle spiral conductor is connected electrically in series to the top spiral conductor; and wherein the bottom spiral conductor, middle spiral conductor and top spiral conductor each comprises a conductor material that has a width in cross section of each turn of the bottom spiral conductor, middle spiral conductor and top spiral conductor and a turn to turn spacing measured in a direction parallel to the base material wherein the width of the conductor material of each turn of the bottom spiral conductor and the width of the conductor material of each turn of the middle spiral conductor is greater than the width of the conductor material of each turn of the top spiral conductor and wherein the turn to turn spacing of the bottom spiral conductor and the turn to turn spacing of the middle spiral conductor is smaller than or equal to the turn to turn spacing of the top spiral conductor.
