This design based on an SR latch and two RC networks is, unlike many alternative solutions, neither complex nor expensive. Single and differential capacitance sensors are widely used to measure linear ...

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 ...

You can use the inherent capacitanceof an LED to make a seriesresonant boost circuit that can create avoltage large enough to light the LED.Depending on the color of the LED, youneed a voltage higher ...

Ever wonder what goes on inside of an electrolytic capacitor? Nick Visic from AiSHi Capacitors shows how these popular capacitors work in this tear-down video from DesignCon. The screw terminal ...

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 ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

Capacitive supplies are very attractive for applications that don't require isolation from the mains supply. Simple, inexpensive, lightweight, and reliable, they run cool and don't generate ...
