Optimization of Spiral Inductor on Silicon

A simulation program is developed based on Grover´s formulas and Greenhouse method to calculate the inductance value and Q-factor for particular dimension and width distribution of spiral inductors. This program changes the width distribution through a predetermined number of quadratic distributions in an attempt to reduce energy losses and improve Q-factor. The result of this program provides a higher Q-factor together with the possibility of reducing the overall dimension of square spiral inductors as compared with conventional designs. The coordinates of dimension for the simulated inductor are also calculated enabling ease of verification and fabrication. Finally, the calculated results are verified by simulating the inductor using HPADS momentum which is MOM based electromagnetic simulator. The ease of use and rapid results of this program can find its attractiveness in wireless communications and related areas.
