ABSTRACT:
A low-value, low-noise, high-Q, high-tolerance inductor is fabricated using multichip module technology, such as high density interconnect (HDI) technology. The inductor has overlapping sections of conductors which contain high magnetic fields between them to reduce the amount of radiated energy and circuit shielding required. The spacing between conductor sections of the inductor is adjustable in order to provide a predetermined amount of field cancellation and thereby achieve a specific inductance value. The inductor shape provides uniformity of current density across the conductor cross section, thus maximizing the Q value of the inductor.
