Performance study of fixed value inductors and their optimization using electromagnetic simulator

Abstract

ABSTRACT:In this article, we present an extensive analysis of the dependence of quality factor, peak frequency, self resonance frequency, and area of a spiral inductor on its layout parameters, while keeping the inductance value constant as opposed to various studies reported. This performance trend study establishes the optimum metal width and number of turns for a specified inductance value and desired operating frequency. We propose here an algorithm for accurate design and optimization of spiral inductors using a 3D electromagnetic simulator with minimum number of inductor structure simulations, and thereby reducing its long computation time.
