A simple model of EMI-induced timing jitter in digital circuits, its statistical distribution and its effect on circuit performance [PDF]

open access: yes, 2003
A simple model has been developed to characterize electromagnetic interference induced timing variations (jitter) in digital circuits. The model is based on measurable switching parameters of logic gates, and requires no knowledge of the internal ...

Low Loss W-Band Packaged Filtering Balun Based on a Modified Quarter-Mode Folded Substrate-Integrated Waveguide Cavity

open access: yesIEEE Access, 2022
A novel packaged filtering balun is proposed by modifying quarter-mode edge and diagonally folded SIW (FSIW) cavities. The TM220 mode is selected to realize the differential signal conversion by using a quarter-mode diagonally FSIW.

Development of Ternary Magnesium Alloys for Laser Powder Bed Fusion: Optimizing Oxide Layer Thickness

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing of magnesium alloys by laser is difficult because the melting point of the oxide layer is much higher than the evaporation temperature of the metal underneath. Making the oxide layer thinner can solve this problem. Alloying magnesium with strontium makes the oxide layer thinner, especially at 0.5 wt%.

Measurement Uncertainty of Radiated Electromagnetic Emissions in In Situ Tests of Wind Energy Conversion Systems [PDF]

open access: yesAdvances in Radio Science, 2018
The electromagnetic (EM) emissions of wind energy conversion systems (WECS) are evaluated in situ. Results of in situ tests, however, are only valid for the examined equipment under test (EUT) and cannot be applied to series production as samples, as ...
