Impact of Si-Based RF IC Spiral Inductor''''s Turns on Quality Factor
硅基RF平面螺旋电感的圈数对品质因子的影响

With the quality factor(Q)'s expression of p lanar inductor on Si-based RF IC's,inductors' value and quality factor are simulated and computed using Aglient software ADS.With the comparison of two group inductors,the impact of increasing turns on quality factor is attained,the quality factor decreases with the increasing turns of inductor.Taking the inductor with value of 3.28nH for example,the turns go up from 2 to 6,while its Q decreases from 4.3(@1.1GHz) to 2.7(@1.4GHz).At the same time,simulations are done using ADS according to theoretical analysis.All conclusion and analysis are usef ul for the planar inductor,and will be one of guide lines of the design of the p lanar inductor.
