A compact circuit model for predicting performance parameters of multi-layer inductors is proposed in this paper. This model, which does not use any fitting and optimized parameters, modeled eddy currents loss in the silicon substrate, skin and proximity effects in metal tracks, which is combined with partial element equivalent circuit (PEEC) method. Excellent agreements are obtained between the modeled...
Using the complex image method (CIM), we have analyzed the frequency and temperature dependencies of substrate eddy currents for single-ended and differential spiral inductors on a lossy silicon substrate. From our analysis, we have derived a set of accurate closed-form expressions for calculating inductances and substrate losses due to substrate eddy currents. Here, we propose a frequency-dependent...
Electromagnetic and thermal analysis for conventional and differential spiral inductors on lossy silicon substrate is rigorously carried out in this paper. Accurate analytical expressions for calculating the frequency- and temperature-dependent inductances and substrate losses due to eddy currents are presented. The simulation results agree well with the measured data. These closed-form expressions...
