The analysis of the multilayer spiral inductors parameters at high frequency

Implementing the spiral inductors in the radiofrequency micrometric integrated circuits is complicated, therefore some prior studies in order to determine their optimum configurations for the circuit in which they will be implemented are necessary. This study is a step forward in the study of spiral inductors, aiming at comparing the monolayer to the multilayer spiral inductors in order to determine their advantages, disadvantages and to reach an efficient configuration. For this purpose, the electric and magnetic phenomena in the spiral inductors, along with their inductance, quality factor, and scattering parameters at high frequency in the 1-20 GHz frequency range will be presented and analyzed.
