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 ...

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 ...

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 ...

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 ...

At low frequency, a transmission line, open at one end, looks like a capacitor. After all, it is just two conductors, the signal path and the return path, with some insulation between them. This is ...

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 ...

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 ...

[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 ...

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 ...

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 ...

As ADAS evolve toward L2+ and even L3 autonomy, domain controllers are facing unprecedented design challenges.
