Abstract This paper presents application of the response surface method for optimal design of integrated planar inductors. An efficient procedure for getting the optimal layout design of octagonal micro-inductors, with the highest value of quality factor, for specified inductance and operating frequency is presented. The presented results prove that the response surface method based on using software tools can provide optimal design parameters with no need for costly fabrication and characterization of integrated inductors that are applied in RF integrated circuits.
