Abstract

In this paper, we develop a design optimization methodology for switchable multi-port spiral inductors in fully integrated wireless systems. The methodology simultaneously maximizes the inductor's performance for multiple inductance values and operating frequencies. We utilize multi-level optimization techniques to efficiently design the geometry of the switchable inductor structure. The methodology can produce designs with significantly larger quality factors than those obtained by optimizing the inductor design for a single inductance value and operating frequency.
