| Abstract(in English) | In order to investigate the effectiveness of an SMA receptacle as wideband measurement electrode for human electrostatic discharges (ESDs), we derived the transfer impedance of a 50-Ω SMA receptacle, and measured its frequency characteristics from 300kHz to 20GHz. With a 12-GHz digital oscilloscope, measurement of discharge currents through a hand-held metal bar from a charged human was made, and thereby the injected currents on the SMA receptacle were reconstructed from the measured transfer impedance. As a result, we found that at a charge voltage of 1500V the reconstructed current waveform agrees well with the observed voltage waveform divided by 50Ω while at a charge voltage of 300V, the reconstructed current oscillates at a frequency of about 7GHz, and also has faster rise time and larger peak than the observed voltage. |
