Abstract :
The design and modeling of a high Q hairpin inductor is presented. The inductor is designed and fabricated using the thick top-level metal (4μm thickness, 14μm away from the substrate) in an IBM 0.5μm SiGe BiCMOS process to provide very high peak Q, approaching 27 from 2 to 4GHz, specifically for integrated voltage-controlled-oscillator (VCO) applications. A broadband lumped-element model is also developed for this structure. The modeling methodology is verified using commercial field solvers (IE3D and ADS Momentum) and hardware measured data, the results show that the derived model correlates with the EM simulation data.
