摘要
采用Matlab软件进行编程计算,结果显示减小电感填充率可以有效增大电感值,而增大电感金属条宽度与间距之比或减小两者之和都可以有效提高电感 Q值。作为实例设计实现了一个电感值为8 nH工作在2 GHz时 Q值为4.34的正方形螺旋电感。
The influence of several main geometric parameters on the performances of spiral inductors is analyzed and discussed, and Matlab programs have been programmed to calculate, the results show that one can increase the inductances by decreasing the fill rate of inductors, and increase the value of Q by increasing the ratio of the widths to the spaces of metal segments or by decreasing the sum of the widths and the spaces of the segments. An (8 nH) Q-4.34 at (2 GHz) square spiral inductor is designed to be as a visual example.
