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 ...

As the Semiconductor industry is growing so does the density of devices on chip. With the increasing density and decreasing spacing rules, the most significant effect that takes birth is parasitic.

[Dr Ali Shirsavar] from Biricha Digital runs us through How to Select the Perfect Output Capacitor for Your Power Supply. Your switching-mode power supply (SMPS) will require an output capacitor both ...

Ferroelectrics are getting a serious re-examination, as chipmakers look for new options to maintain drive current. Ferroelectric materials can provide non-volatile memory, serving an important ...

Engineers usually have access to signal and function generators, as well as frequency counters and oscilloscopes, but they may not have access to capacitance or inductance meters. Using the test setup ...

Researchers from Skoltech, MIPT, and the RAS Institute of Nanotechnology of Microelectronics have achieved a five-fold increase in the capacitance of carbon nanowalls, a material used in the ...

Energy saving: artist’s impression of the gate material with negative capacitance. (Courtesy: Ella Maru Studio) By exploiting a curious effect called negative capacitance, researchers have designed a ...

Reducing back-end-of-line (BEOL) interconnect parasitic capacitance remains a focus for advanced technology node development. Porous low-k dielectric materials have been used to achieve reduced ...

Appropriately cut quartz crystals can be used as high-quality electromechanical resonators. Their piezoelectric properties (voltage across the crystal deforms it; deforming the crystal generates a ...
