Modeling and optimization of a solenoidal integrated inductor for RF ICs Abbas Golmakani1,2, Khalil Mafizejad1,2, Milad Razzaghpour2, Abbas Kouzani3 1Ferdowsi University of Mashhad, Mashhad, Iran 2Sadjad Institute for Higher Education, Mashhad, Iran 3School of Engineering, Deakin University, Geelong, Victoria, Australia Received 1 July 2009; accepted 6 October 2009 Abstract – A solenoidal structure for implementation of on-chip inductors is presented. An electromagnetic simulator is used to simulate several different-size inductors for up to 20 GHz. Additionally, artificial neural network models are developed for different inductor topologies to speed up inductors optimization process. Finally, it is demonstrated that the solenoidal inductor exhibits a better overall performance in comparison to the conventional multi-layer spiral inductors demonstrating its potential for RF ICs. © 2009 Wiley Periodicals, Inc.
