Abstract :
The definition of common-mode loop impedance is proposed instead of the ambiguous definition of common-mode impedance. Moreover, a noninvasive measurement method to characterize the common-mode loop impedance using dual clamp-on current probe is presented herein. The frequency responses of the current probes are deembedded through a calibration procedure. Independent direct measurements using a network analyzer corroborate the validity of the Dual-Current-Probe Method.
