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 ...

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 ...

Capacitive sensor interfaces are critical to the accurate measurement of physical parameters such as pressure, humidity, and force across a broad range of applications including biomedical devices, ...

Electronic circuits are integral parts of nearly all the technological advances being made in our lives today. Television, radio, phones and computers immediately come to mind, but electronics are ...

As discussed in the first part of the article, the accuracy with which sensor capacitance can be measured using absolute capacitance measurement has a significant dependency on the accuracy of the ...

A recently filed patent (Publication Number: US20230314495A1) describes a capacitance measurement circuit that includes an analog front-end circuit, a parasitic capacitor, an analog to digital ...

As the world shifts toward sustainable transportation, electric vehicles (EVs) have emerged as a key solution to reducing greenhouse gas emissions. However, one major hurdle remains: efficient and ...

In 2008, Bob Pease exchanged e-mails with Linear Technology’s Mark Thoren, me, and a few other friends. The subject was how an amplifier will oscillate if you put a capacitive load on it. Bob knew ...
