摘要
利用Maxwell 2D/3D软件对矩形螺旋芯片电感进行建模仿真,分析了矩形螺旋电感的绕线宽度、绕线间距、导体厚度以及线圈匝数四个结构参数对电感值和Q值的影响。仿真结果表明,在电感尺寸确定时,线圈间距小能够使电感值大而且Q值也大;在一定条件下,当匝数为4.5匝左右,线宽为48μm左右,厚度为70～80μm时可获得性能较佳的电感。
Model building of simulation was carried out for a rectangular spiral chip inductor by using Maxwell 2D/3D software.Analysis was made to four structural parameters such as winding width,winding span,conductor thickness and winding number for the rectangular spiral inductor which impacted on induction value and Q value.Simulation result shows that small winding span makes induction value and Q value large with inductor dimension determined and better performance of induction can be obtained under the conditions of around 4.5-turn winding number,around 48-micron winding width and thickness range from 70 to 80 micron.
