Abstract

This work investigates the impact of dielectric loading on the RF performances of integrated VCO and PLL systems. Both On-Chip and System-Level (On-Board) experimental characterizations are carried out to determine influence of various substances (resins, salted water, petroleum, sugar mixture) on frequency variations, taking into account the importance of mechanical fixture. Calibration and monitoring aspects are discussed towards real-time measurement of aqueous concentrations of liquids for medical applications.
