Abstract :
In this paper the basic system design constraints for the inductive power and data link are shown. The limiting factors for the choice of quality factors, coil inductance and carrier frequency are evaluated through analytical methods and simulations. The impact of the analysis on the required rectifier structure is also discussed. The analysis is focused on the development of a miniature biomedical sensor device whose outer dimensions shall not exceed 5-by-5 mm.
