Abstract :
In this paper frequency dependencies of delta-I noise caused by variations in on-chip switching activity has been studied for a complex computer system board with multi-chip module, especially the impact of coincidences with resonances of the power distribution system. The switching cycle has been varied in case of a single delta-I step and the effect of repeated delta-I steps and variations of the delta-I repetition frequency and the duty factor have been analyzed
