Abstract

In this paper, we examine the design of planar inductors and consider an expansion of the conductor to reduce its resistance. An increase in the number of turns increases the proximity effect, capacitive coupling, and skin effect. The resulting effect will translate into an increase in the area occupied by the inductor and a decrease in the inductors' performances. In order to solve such difficulties, an alternative approach is to design tapered inductors. For the same electrical and geometrical characteristics, a tapered inductor occupies a larger area than a standard inductor. Our approach consists of designing a new concept regarding tapered planar inductors that occupy the same surface and maintain the same electrical characteristics as the standard planar inductor regarding the following topologies: circular, hexagonal, and square. The results obtained show that impedance is more important in the case of the tapered inductor. Higher impedance implies smaller current and hence smaller parasitic effects of the capacitance series and proximity effect.
