Summary:
Very fast transients due to micro-gap discharges as low voltage electrostatic discharges (ESDs) were investigated in time domain. We previously developed a 12GHz wideband measurement setup consisting of a distributed constant system, while the observed transients due to micro-gap discharges had very fast rise time of 34 ps or less, which reached the limitation on our system. In this paper, we proposed a method for estimating wideband transients beyond the measurement limit by using the transmission loss of a high performance coaxial transmission line. This method was also validated by estimating an impulsive voltage waveform with rise/fall time of 16ps from the waveform measured through a semi-rigid coaxial cable with a length of 10m.
