Abstract

This paper presents an investigation into the use of high aspect ratio conductors to improve the performance of RF inductors. Also presented is a review of commercially available technologies for RF chip inductors. The objective is to provide an analysis of the inductor parameters against which the high aspect ratio coils can be compared. A range of inductors from 10nH to 100nH in varying footprint areas is designed for fabrication using a novel rapid prototyping technique. High frequency (1GHz) 2-D and 3-D finite element modelling is used to provide an understanding of the behaviour of the high aspect ratio coils. Results from this analysis predict improvement of 15-30% in Q-factors compared planar equivalents.
