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 ...

Every now and then you need to make your own capacitor. That includes choosing a dielectric for it, the insulating material that goes between the plates. One dielectric material that I use a lot is ...

Most simple circuits you'll find for measuring reactive components cover only a limited range of component values. Here's a circuit built from a handful of inexpensive parts that will let you measure ...

Megger’s new CDAX 605 test set measure capacitance and dissipation factor at high voltages. Faster and easier to use than self-balancing capacitance bridges, the CDAX 605 combines an exceptionally ...

Ceramic capacitors are pretty much the pixie dust of the electronics world. If you sprinkle enough of them on a circuit, everything will work. These ceramic capacitors aren’t the newest and latest ...

An optimal way to determine an op amp's input capacitance. Steps involved in making the input-capacitance measurement. 1. With a series resistor at the op-amp input, the input capacitance of the op ...

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 ...

This paper defines a method to measure the chip die pad capacitance using time delay reflectometry (TDR). This method is useful for measuring the low-value capacitance that is present at the end of a ...

Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

Two new ICs are described as fully integrated devices that offer direct capacitance-to-digital and impedance-to-digital conversion. The single-chip AD7745 integrates all stages of ...

If you’re the person tasked with controlling the level of fly ash in collection hoppers, you know how difficult the application can be. What at first looks like a simple measurement quickly proves to ...
