Supercapacitors have emerged as a promising energy storage technology, offering high power density, fast charging and discharging rates, and long cycling life. They have the potential to revolutionize ...

The capacitance of a classical conductor is determined solely by its geometry. When charged, the electrons distribute in space in a manner that minimizes their electrostatic energy. Quantum mechanics ...

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 ...

The race to build reliable quantum computers is fraught with obstacles, and one of the most difficult to overcome is related to the promising but elusive Majorana qubits. Now, an international team ...

Power MOSFET capacitance isn't a fixed value—it's a highly non-linear function of voltage that standard LCR meters struggle to capture accurately at operating biases. By combining the waveform ...

Ferroelectric materials, which were discovered nearly a hundred years ago, and have led to a huge range of applications, including digital information storage and neuromorphic computing, are still not ...

Reducing the parasitic capacitance between the gate metal and the source/drain contact of a transistor can decrease device switching delays. One way to reduce parasitic capacitance is to reduce the ...

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.

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 ...

[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 ...
