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 ...

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.

In a chip, resistance (R) is how difficult it is for current to flow. For example, the longer the wire, the higher the resistance. The material also matters: copper wire has more resistance than ...

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 ...

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 ...

Scanning microwave microscopy (SMM) is a scanning probe method that uses the S11 parameter to calculate the local tip-sample microwave impedance. This impedance is affected by the sample’s local ...
