ABSTRACT:
The present invention relates, in general, to a method and apparatus for creating improved inductors which can be adapted for use with electronic oscillators. The method includes at least the following: forming a first coil; forming a second coil, such that the second coil is proximate to the first coil and such that a magnetic flux from the formed outer coil will link with a magnetic flux of the formed second coil; and connecting the first coil to the second coil in electrical parallel. The apparatus includes at least the following: a substrate; and a composite inductor having at least a first coil with an associated inductance and resistance and a second coil with an associated inductance and resistance, with the first coil and the second coil connected in electrical parallel but formed in the substrate such that said composite inductor has resistance substantially less than the combined resistances associated with the first coil and the second coil. The composite inductor further includes the first coil and second coil connected in electrical parallel but formed in the substrate such that the composite inductor has inductances substantially equivalent to the combined inductances associated with the first coil and the second coil. The apparatus can be utilized to form an oscillator implemented in an integrated circuit.
