My colleagues and I focused on a less visible part of the problem: the components that deliver power to those transistors.
A chip needs more than electricity. It needs electricity supplied at the right voltage, with fluctuations kept under control. Making the hardware that does this smaller is an important challenge—and one that led my colleagues and me to build tiny magnetic devices called stripline microinductors.
In our study, we fabricated these devices using a composite of nickel and iron oxide nanoparticles. Our measurements showed more than twice the inductance of comparable devices without a magnetic core. The broader question behind this work is how to bring useful magnetic materials into the small structures used in semiconductor manufacturing.
The research was conducted at the University of Florida with my coauthors Brenden M. Mears, Noah Morgan, Jennifer S. Our study, now published in the Journal of Micromechanics and Microengineering, brought together expertise in materials synthesis, microfabrication and electrical characterization.
Voltage regulators convert an incoming electrical supply into the voltage a circuit needs. In many switching regulators, an inductor temporarily stores energy in a magnetic field and helps control changes in current. Together with other components, it turns rapidly switched electrical power into a steadier supply.
Inductors can be difficult to shrink. Reducing their dimensions generally reduces the inductance available from a particular design. One way to compensate is to add magnetic material around the conductor.
