Experimental electrical double-layer capacitances of porous carbon electrodes fall below ideal values, thus limiting the practical energy densities of carbon-based electrical double-layer capacitors.

Have you ever found the need to measure the capacitance of a capacitor? No multimeter handy (for shame)? Well, as it turns out you can actually measure capacitance using your Arduino Uno, with no ...

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.

As the technology node decreases, meeting inter-wire or coupling capacitance becomes extremely critical and challenging in SOC design. Shrinking technology node leads to increase in dielectric values, ...

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 ...

Improving the capacitance of supercapacitors requires gaining control over ion behavior inside carbon nanopores. This study demonstrates that ...

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 ...

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 ...

This rule of thumb estimates the capacitance per length of all 50 Ohm lines in FR4. Remember: before you start using rules of thumb, be sure to read the Rule of Thumb #0: Use rules of thumb wisely. At ...

A research team led by Prof. Huang Xingjiu from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences constructed a highly stable solid contact calcium ion-selective electrode.
