Integrated spiral inductor with substrate silicon in a buck converter

Abstract

In this paper, we discuss the design and modelling of a spiral inductor with silicon substrate. The equivalent electrical model approved of the integrated spiral inductor acquires into account the inductance and quality factor. The performance of the inductance and quality factor values is supported on the mathematical study of the effect geometrical elements on the spiral inductor. The results simulation based on the MATLAB software. Finally, is discussing after simulation about the integrated spiral inductor into a DC-DC converter by PSIM 6.0.
