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 ...

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 ...

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 ...

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 ...

WEST LAFAYETTE, Ind. – Researchers have experimentally demonstrated how to harness a property called negative capacitance for a new type of transistor that could reduce power consumption, validating a ...

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, ...

Op amps with low input capacitance are required in applications such as smoke detectors, photodiode transimpedance amplifiers, medical instrumentation, industrial control systems, and the piezo-sensor ...

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 ...

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 ...
