Correlation considerations II: Real HBM to HBM testers

This work expands on earlier real HBM initial front rise (0 to 15 Volts) sub-nanosecond measurements with faster equipment using both 1 Ω and a 50 Ω resistance current sensors to identify the complete range of peak current and risetime of HBM discharges. Several accurate high-speed measurements were made which show real HBM being significantly faster, and that they can have higher peak currents than the present HBM test specification.
