What is the physical model for planar spiral inductors on silicon?

Abstract— This paper presents a physical model for planar spiral inductors on silicon, which accounts for eddy current effect in the conductor, crossover capacitance between the spiral and center-tap, capacitance between the spiral and substrate, sub-strate ohmic loss, and substrate capacitance.

Are planar spiral inductors scalable?

In this paper, a physical model for planar spiral inductors on silicon is presented. The characteristics of each component in the model have been investigated extensively. The physical phe-nomena important to the prediction of are considered and an-alyzed. The scalable inductor model shows excellent agreement with measured data.

How to calculate total inductance of a planar spiral inductor?

Greenhouse’s scheme to compute the total inductance of a planar spiral inductor takes into account the self-inductance of each segment, as well as the mutual inductance of each parallel (nearest neighbor and otherwise) pair of inductor segments, where each segment is rectangular. Therefore, the total inductance of a planar spiral inductor is

What is the design structure of a planar inductor?

Design structure of the planar inductor. The planar inductor consists of a multi-turn planar copper spiral on a CCL substrate with the via-filled and the top and bottom screen-printed iron-based alloy-epoxy resin pastes. To achieve miniaturization, CCL substrates were used as the substrates.

How can a square planar spiral inductor be expanded?

This analysis can be expanded by replacing the planar spiral inductor segments with symmetrical current sheets, with equivalent current densities. For a square planar spiral inductor, four identical current sheets can be identified. The current sheets on opposite sides are parallel to each other, while the adjacent ones are orthogonal.

Are planar spiral inductor-based Transformers embedded in integrated circuits?

Armed with the concepts of mutual capacitance and inductance between parallel segments of a planar spiral inductor, planar spiral inductor-based transformers embedded inside integrated circuits can now be examined.
