This paper presents the dimensioning and modeling of a circular inductor integrated in a Boost micro converter. At first, we define the characteristics of the Boost micro converter, which is the starting point for the design our component, taking into account the electrical and magnetic characteristics of the materials selected. The second, a Boost micro converter schematic simulation coupled with ideal and integrated inductor was presented. This conceptual model of the Boost is best understood in terms of the relation between voltage and current of the inductor. Finely, we have simulated the electromagnetic effects in integrated inductor in the air, and with substrate using the finite element method.

“…This structure was suitable for applying to the fabrication process of metal -embedded SU-8 slab because a magnetic core can be simultaneously electroplated around the winding in a single step, which could help simplify the process. Furthermore, the advantages of this structure include thermal sink [13], [14] and flux leakage reduction because of the presence of the metal core around the inductor structure. According to this design, the winding was 250-μm thick, and the whole structure height including insulation layer and magnetic core was less than 400-μm thick, which is good in on-chip inductors for micro power converter applications.…”

This work presents new fabrication technique for micro power-inductors by using metal-embedded SU-8 slab techniques. This techniques used X-ray lithography to fabricate high aspect-ratio LIGA-like micro-structures in form of embedded structure in SU-8 slab and applied for inductor’s winding fabrication with aspect-ratio of 10. Thishigh-aspect ratiostructure can provide very low resistance winding but preserve small form factor and low profile. Inductors were designed as pot-core structures with8 μm-thick permalloy core and 250 μm-thick copper winding. 4-types of inductors were fabricated including 3, 5, 10 and 16 turns in the area of 1.8 mm2 to 9.5 mm2. All inductors have overall heights of 370 μm, measured inductance value in a range of 70 nH to 1.3 μH at 1 MHz and DC resistance value of 30 mΩ to 336 mΩ for 3 turns to 16 turns respectively. From this result, high aspect-ratio inductors show<span style="font-size: 10.0pt; font-family: 'Times New Roman','serif'; mso-fareast-font-family: Calibri; mso-bidi-font-family: 'Cordia New'; mso-bidi-theme-font: minor-bidi; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: TH;"> good results including low-resistance, high inductance, and a small form factor as expected.

“…The high demand for decreasing the size and weight of communication devices has been a strong incentive for researchers to improve monolithic inductors [1,2]. The inductor is the least compatible passive device with silicon integration and subsequent scaling [3] and is often used in RF (radio frequencies) applications as a discrete device rather than an integrated circuit into the silicon chip [4]. The bulkiness of the discrete inductors has been a disadvantage for use in portable electronic devices, and hence inductors that incorporate magnetic films to boost inductance densities have researched recently [4].…”

In this work, the design and modeling of the solenoid inductor are discussed. The layout of integrated inductors with magnetic cores and their geometrical parameters are developed. The quality factor Q and inductance value L are derived from the S-parameters and plotted versus frequency. The effect of solenoid inductor geometry on inductance and quality factor are studied via simulation using MATLAB. The solenoid inductor geometry parameters considered are the turn's number, the magnetic core length, the width of a magnetic core, the gap between turns, the magnetic core thickness, the coil thickness, and solenoid inductor oxide thickness. The performance of the proposed solenoid inductor integrated with FeNiCo is compared with other solenoid inductors.
