Detailed analysis of high-quality symmetrical octagonal spiral inductors on Si substrate
Research studies of symmetrical spiral inductors for silicon technology have become very important and challenging. In this article, we attempt to give a detailed explanation of how symmetrical spiral inductors help to improve the quality factor (Q) as compared to conventional nonsymmetrical inductors. The experimental results are presented to verify our theory. (c) 2005 Wiley Periodicals, Inc.
