Abstract
Abstract Planar spiral windings have garnered a significant amount of attention recently due to the popularity of slim consumer electronics combined with their low-profile, high reproducibility, and simple manufacturing. Unfortunately they still suffer from high internal capacitance which limits their use at high frequencies. This work presents the novel inverse Track-Width-Ratio (TWR) planar structure, which greatly reduces the undesired capacitance of multi-layer planar spiral windings by changing the turn widths. The amount of overlapping copper is ultimately reduced with the proposed technique, especially in the areas where the capacitance is the highest, resulting in significantly improved performance. Analytical models for the resistance of planar spiral windings with inverse TWR employed are presented and used as inputs into Finite Element Analysis to predict the capacitive behaviour of the structure. These results are compared to experimental results obtained from an impedance analyzer and a capacitance reduction up to 50% is exhibited, with a reduction in ac resistance by 20%.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
