An Optimization Technique for Planar Spiral Inductor Based on the Inductor''''s Physical Model and Genetic Algorithm
一种基于物理模型与遗传算法的平面螺旋电感的优化技术

An efficient optimization technique for CMOS RF planar spiral inductor is presented on the basis of the physical model of an inductor as well as the genetic algorithm.With it,it is unnecessary to design an optimal high Q inductor by means of the contour plots of Q ,which is high cost and time consuming as we all know.Via the new technique,the computation efficiency is improved greatly,because we haven't to compute each design scheme.The calculated result is in agreement with the measured one,with the error within 5%.By using the technique,the same optimal design can be obtained under the same condition as that obtained by using contour plots.As a matter of fact,because of the flexibility of our technique,the acturally best design can be only obtained by using this technique instead of by the contour plots of Q .
