Abstract

The demand for efficient, lightweight consumer products created the need for miniaturization
of passive components especially inductors which are some of the bulkiest parts of an integrated system. The purpose of the work described here was to study toroidal inductor structures since they were compact and self-shielding. Toroidal
inductors were modeled using a commercial electromagnetic simulator. The results
show that these structures have good characteristics in terms of inductance, quality
factor and area. Three different structures are fabricated and experimentally characterized
using the HP Vector Network Analyzer. We also make several observations about the effect of the placement of each pair of top and bottom metal strips with respect to each other on the flux linkage and hence, the inductance and quality factor of the inductor.
