“…In addition, other methods for further enhancing the Q-factor have been explored, such as adding a patterned ground shield, backside scooping technology, and micromachined ICs. The RF and mixed-signal IC design process requires accurate inductor models that can be included in the circuit simulation along with the entire IC design [14][15][16][17]. Therefore, a frequencyindependent equivalent circuit model is needed to represent the electrical performance of an inductor.…”

In order to provide excellent performance and show the development of a complicated structure in a module and system, this paper presents a double air-bridge-structured symmetrical differential inductor based on integrated passive device technology. Corresponding to the proposed complicated structure, a new manufacturing process fabricated on a high-resistivity GaAs substrate is described in detail. Frequency-independent physical models are presented with lump elements and the results of skin effect-based measurements. Finally, some key features of the inductor are compared; good agreement between the measurements and modeled circuit fully verifies the validity of the proposed modeling approach. Meanwhile, we also present a comparison of different coil turns for inductor performance. The proposed work can provide a good solution for the design, fabrication, modeling, and practical application of radio-frequency modules and systems.

“…The frequency independent L / C equivalent model, the left procedure of Fig. 2, is proposed for estimating total inductance, capacitance and SRF of spiral [14]. In this paper, we focus on the frequency‐dependent equivalent model, providing conduct‐, dielectric‐loss and Q ‐factor, as well as inductance, capacitance and SRF.…”

This study presents a new equivalent circuit modelling methodology for various-type spiral resonators in printed circuit board environment. The N-turn spiral resonator can be decomposed into an N Π-equivalent circuit model, and each Π-model is comprised of a series inductance, parallel capacitance, two shunt capacitors and the resistances of the conductor and dielectric. Both the inductance and capacitance of the equivalent circuit are calculated by the proposed formulas, which are based on the electromagnetic theory. It has been demonstrated that the proposed equivalent circuit model of the spiral resonator is well matched in S-parameters, Q-factor and inductance values as well as in self-resonance frequency values within 8% tolerance with measurement and full-wave electromagnetic field solver.

Parasitic effects significantly interfere with systematic model‐parameter extraction, making linear fitting of spiral inductors challenging when the number of turns exceeds 6, as seen in existing works. Based on the single‐π model, we propose a parameter‐extraction technique using an additional three ladder R–L ladder network in series to more accurately predict skin and proximity effects. Compared to the latest enhanced π‐circuit model, our proposed model with parameter‐extraction technique in multi‐laps inductors accurately predicts the characteristics of series inductance (Leff) and quality factor (Q) across the self‐resonant frequency, especially at the peak. This model could be used directly for the model of the on‐chip inductor in both academic and industrial fields.
