This measurement is ideal for switching characterization of wide-bandgap semiconductors, which are progressively improving switching speeds of power electronic circuits and require a PCB design with low parasitic inductance. A design workflow for system integration of a differential Rogowski coil, including the necessary signal processing circuits onto a printed circuit board is provided. Different parasitic effects have been analyzed, and an amplifier topology for high bandwidth and superior Common Mode rejection is presented. The calculations are verified by simulation and measurements.}, language = {en} }
