The degradation of semiconductor CMOS structures due to the action of overloads in the form of ultra-short video pulses is investigated. It is shown that these video pulses in Schmitt triggers produce a change in the threshold voltages and a contraction of the area of uncertainty. In buffer elements, intense phase noise occurs, while in RC generators there is a change in the length and repetition frequency of the pulses generated. Experimental equipment for determining the critical parameters of the actions of ultra-short video pulses on a sample of digital microcircuits and CMOS structures is described.
