In this paper, we discuss the design and modeling of a solenoid inductor with a magnetic core. The equivalent electrical model approved of the integrated solenoid inductor acquires into account the inductance and quality factor. The optimization of the inductance and quality factor values is based on the numerical analysis of the influence of the geometric parameters on the electrical characteristics of the solenoid inductor. The results simulation based on the MATLAB software. Finally, is discussing about the integrated solenoid inductor in a buck converter DC-DC, simulation results present by PSIM.

The recent evolution in radiofrequency (RF) devices and integrated circuit technologies greatly expanded the number of wireless applications . This expansion generated a growing demand for semiconductor manufacturers, requiring a higher integration in RF circuits. However, as passive device performances are directly tied to their geometry (especially for inductors), they end up being the bottleneck on radiofrequency circuitry integration. Inductors are of utmost importance in radiofrequency integrated circuits . These devices are employed in critical building blocks of radiofrequency integrated circuits such as intermediate frequency filters , low-noise amplifiers , voltage-controlled oscillators , and power amplifiers . Current on-chip spiral inductors suffer from large parasitic and area for a meager value of inductance and quality factor . The need to overcome these issues has led to the development inductors with new geometries housing magnetic cores that show an enhanced inductance compared to the air core coil. In this paper, the behavior of solenoid inductors is systematically studied and the impact of the geometrical parameters on its inductance and quality factor. The principal object of my paper is to detail all the phases of design and modeling of a solenoid inductor in order to attain its realization and integrate it into a micro-converter . This structure increases the quality factor value while reducing the constituent dimensions with a small manufacturing cost . Design of solenoid inductor A simple solenoid inductor consists of a metal wire wound around a magnetic core, as shown in figure 1 . Geometric parameters used in the schematic of an integrated solenoid inductor are as follows: the number of turns of the coil N, length of the coil lc, length of the magnetic core (air core) lm, spacing between turns s, width of the magnetic core wm, width of the air core wa, width of coi [...]
