Spiral inductors inductance computation and layout optimization

The inductance computation and layout optimization of spiral inductors are still research topics of great interest and actuality, especially in radio frequency integrated circuits domain. Our research work focuses on the extensive topics of this research area for several years. To this purpose we have create a software program, named CIBSOC (Spiral Inductors Inductance Computation and Layout Optimization), dedicate to de inductance computation and to layout optimization for spiral inductors. We use a wide range of inductors in the applications made with our program; we compare our applications results with measurements results existing in the literature and with a commercial field solver results in order to validate our program. Our program is accurate enough, has a very friendly interface, is very easy to use and it computes problems in a very sort running time compared with other similar programs. Since spiral inductors tolerance is generally on the order of several percent, a more accurate program is not needed in practice. The program is very useful for the spiral inductors design, because it compute theirs inductances with high accuracy; and also for the spiral inductor optimization, because it affords optimal solution for spiral inductor layout dependent on the users´ needs.
