摘　　要：为了提高螺旋电感的品质因数,综合多种变量进行高效的优化,提出一种GP优化的方法来得到螺旋电感品质因数最佳值。该方法通过matlab仿真分析了集成电路螺旋电感的一种物理模型,找出了对螺旋电感品质因数有影响的几个变量。在此基础上对螺旋电感模型整体进行了建模,在确定的电感值及一定限制条件下,用matlab进行螺旋电感品质因数Q的严格的GP优化。仿真结果表明,与遗传算法和等Q值线相比,GP优化的方法分别提高了14.5%和20.2%。In order to improve Q factor of inductor and optimize efficiently by synthetically considering multi-variables, a method called GP （Geometric Programming）optimization was used to get the best quality factor of spiral inductor. By analyzing the physical model of inductor through matlab, several variables which may affect the quality factor of inductor were found. With these variables and identified design requirements, GP modeling and optimization can begin. Simulation results show that compared with genetic method and image method, GP method can improve the quality factor of 14.5%and 20.2%.
