Inductance Enhancement Using Nested Inductor Topology for RF and Voltage Regulators Applications

The increasing demand of inductors in various industries reflects the attention of scientific communities to identify various solutions based on the magnetic flux density. This paper presents the design and simulation analysis of various inductors being investigated in COMSOL. The performance of straight line and circularly bent shaped inductors (nested inductor) is investigated based on simulation of the same dimension, size inductor in COMSOL. The achieved results predict that by changing the shape of the inductor from straight line to circularly bent, keeping all other parameters including permeability the same the inductance of the inductor is increased from
$0.38568\mu\mathrm{H}$
. to
$0.7525\mu\mathrm{H}$
. The magnetic flux density in a straight-line inductor is increased from 4mT to 6mT in a circularly bent or nested inductor.
