چکیده
This paper proposes an optimization methodology of on-chip spiral inductors. Characteristics of spiral inductors heavily depend on layout structures. We then formulate the characteristics with structural parameters and frequency as variables using a response surface method. The proposed method uses S-parameters to express inductor characteristics, and hence our method is independent of spiral geometries and equivalent circuit models. We explain the procedure of inductor optimization and demonstrate a design example.
