The USB (Universal Serial Bus) specification requires a connected USB device to present a load to the host or hub of no greater than 10 µF in parallel with 44Ω, including the effects of any bypass ...

The use of air-break disconnect switches to interrupt the capacitive currents associated with open‑ended bus runs and short lines is common practice. In most cases, the current magnitude is no more ...

Metal halide perovskites are soft-lattice semiconductors with inherent high ionic concentrations. Their X-ray sensitivities are several orders of magnitude higher than semiconductors such as silicon, ...

The first major performance item to review is large-signal load-transient response performance. Here, a large-signal phrase is used in contrast to a small-signal. A small-signal transient literally ...

Ceramic capacitors are pretty much the pixie dust of the electronics world. If you sprinkle enough of them on a circuit, everything will work. These ceramic capacitors aren’t the newest and latest ...

Capacitance at the input of the DC-DC converter plays a vital role in keeping the converter stable and playing a role in input EMI filtering. Large amounts of capacitance at the output of the DC-DC ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

Leakage current has been a leading cause of device failure in DRAM design, starting with the 20nm technology node. Problems with leakage current in DRAM design can lead to reliability issues, even ...

Find a downloadable version of this story in pdf format at the end of the story. In any industry, there are applications whose failure could mean lost revenue and increased annoyance. In very few ...

The vast majority of bearing failures in electric motors and electric motor-driven equipment are due to mechanical and thermal causes. However, currents that flow through induction motor bearings can ...
