In-Circuit Impedance Measurement Setups of Inductive Coupling Approach:
AbstractIn-circuit impedance measurement provides useful information for many
EMC applications. The inductive coupling approach is a promising
in-circuit impedance measurement method due to its non-contact
characteristics and simple on-site implementation. Many measurement
setups of this approach were reported. However, a comprehensive survey
and comparison of these setups have not been found in the literature.
This paper reviews these setups in terms of their characteristics,
limitations, and applications. In addition, recommendations for future
research are also presented.
