Abstract

This paper presents magPEEC, a new 3D electro-magnetic modeling technique that extends existing PEEC approach to analyze arbitrary conductor-magnet structures by accounting for fictitious magnetized currents on magnetic material surface. Applications of magPEEC for magnetic-cored RF IC inductors are discussed with examples of stacked spiral inductors in 0.18 μm CMOS. The observed upper-limit effect of enhancing inductance by increasing magnetic permeability is also discussed.
