Abstract
The radio frequency (RF) impedance of a metal trace at gigahertz frequencies is reduced by forming the metal trace to have a base region and a number of fins that extend away from the base region. When formed in a spiral configuration having a number of loops, the metal trace forms an inductor with an increased quality factor (Q).
