Claim Text:
1. A circuit configuration for decoupling a load circuit from AC noise propagating through a conductor leading to the load circuit, the circuit configuration comprising: at least one circuit element having a plurality of superimposed layers, wherein at least one conductive pathway traverses through the circuit element for making electrical connections along the conductive pathway between points that are displaced from one another at least on one surface of the circuit element, the conductive pathway having an impedance characteristic; wherein the circuit element attaches to the load circuit on one surface and to a package base on the other surface; wherein the impedance characteristic is defined in part by a decoupling circuit comprising at least one capacitance coupled in parallel with the load circuit and at least one inductance coupled in series with the conductive pathway, wherein the capacitance and inductance form a low pass filter attenuating noise signal components at frequencies above a predetermined frequency, thereby decoupling the load circuit from said noise signal components; wherein the inductance is provided by first and second conductive coils magnetically coupled with each other to form a transformer by overlapping a first portion of the first conductive coil and a first portion of the second conductive coil around a common lumen so that the overlapping portions occupy a same circuit area, wherein the first conductive coil further comprises a second portion that is continuously formed with the first portion of the first conductive coil through a first transition portion and the second conductive coil further comprises a second portion that is continuously formed with the first portion of the second conductive coil through a second transition portion, wherein the first and second portions of the first conductive coil are disposed on different layers of the plurality of superimposed layers and the first and second portions of the second conductive coil are disposed on different layers of the plurality of superimposed layers, and wherein the first transition portion shares a substantially similar cross-section with the first and second portions of the first conductive coil and extends in a direction between the first and second portions of the first conductive coil that is not perpendicular to either the first or second portions of the first conductive coil, and the second transition portion shares a substantially similar cross-section with the first and second portions of the second conductive coil and extends in a direction between the first and second portions of the second conductive coil that is not perpendicular to either the first or second portions of the second conductive coil.
