Staggered microvias are microvias whose position on each layer is not directly above or below another microvia i.e. the position of each microvia on the corresponding layer is offset.

Gedankinexperiment: electron flow in copper. Consider the paths electrons take moving through a copper conductor; conductor surfaces and through bulk/cross-section. Is it possible to tag electrons, guide each in separate groups, so that multiple and isolated paths are followed that do not cross? In other words, consider a street with automobiles traveling in opposite directions without accidents, include bicycle paths, and pedestrian paths, all traveling at different speeds, avoiding collision. Through a copper conductor, can different speed of electron flow isolated from each other for signal transmission?

Jerry, It may be a technically but as I understand the physics, electrons do not “flow” through a conductor. In other words a given electron does not start at one end of a wire and under the influence of an electric field that creates a potential, move along the wire. What happens is the electron “excites” it neighboring electron effectively staying in its place. This “excitement” continues from one electron to the next without the electrons physically moving down the conductor. Thanks for your provocative gerankinexperiment.

Automatic coupling system in bullet train 🚅

Italy hosted the first experiment of magnetic levitation carried out on existing (not modified) railways. This technology is being developed by IronLev. It exploits the intrinsic properties of the material constituting existing railroad tracks to establish a repulsive force of magnetic origin able to maintain a load suspended. Surprisingly, the generation of this force does not require electrical currents; rather, a special configuration of permanent magnets is adopted, which simultaneously prevents derailment risk. The test was undertaken with a 1-ton locomotive travelling at 70 km/h for 2 kilometers. #EnergyTransition #trains #trasport #cleantech

If you are using a rail-to-rail input op amp, your circuit may be impacted by input crossover distortion. The article below explains the difference between traditional rail-to-rail amplifiers and zero-crossover amplifiers. Measured results that show the impact of crossover distortion on total harmonic distortion are also covered. I hope this article helps you to better understand the benefits and limitations of traditional rail-to-rail amplifiers and zero-crossover amplifiers. https://lnkd.in/gR3r7EQ9

𝗠𝗮𝗴𝗶𝗰 𝗶𝗻 𝗲𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 ✨ Is there a difference between Rat-race coupler and Magic Tee? They have quite similar functionality, but differ in the implementation: planar vs. waveguide. A Magic Tee is a hybrid microwave component that splits and combines signals while isolating certain ports from each other. It is used to direct signals in systems like radar, ensuring that transmitting and receiving signals don't interfere with each other while sharing the same antenna. ❓ Have you worked with Magic Tee? https://lnkd.in/d2gTUfu
