Abstract :
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 offer the great insights into lossy substrate effects as a function of both the frequency and temperature on the performance of on-chip spiral inductors
