A simple planar inductor

In Integrated Circuit design and MMIC design, integrated planar inductors are used frequently. These inductors have typically lower quality factors. However, in a variety of applications planar inductors can be used effectively. The simplest planar inductor is a length of high characteristic impedance microstrip line. A brief paper published by Signal Processing Group Inc.,provides design equations for this type of structure. Interested readers can view the paper at SPG’s website, http://www.signalpro.biz on the engineering pages web page.

We design and deliver analog and RF/wireless ASICs and modules using state of the art semiconductor, PCB and assembly technologies. Please contact us at spg@signalpro.biz for a quote and a proposal.
