Capacitors are classified according to their dielectric’s type. Electrolytic capacitors are popular in power electronic circuits, due to their high volumetric efficiency and excellent price ...

Capacitive sensors are found in a wide range of equipment, from consumer electronics to industrial/process control. Touch buttons are increasingly found in lamps and dimmers. Motion detectors can ...

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 ...

Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...

An AC bridge circuit can be used to measure the unknown capacitance of a sensor, such as a relative humidity (RH) sensor. Some RH sensors have a transfer function of capacitance vs %RH. Usually the ...

Thoughtful reader Raymond Laagel of Mulhouse, France sent a note with a proof of a Design Idea we published back in 2010. The DI was called Circuit measures capacitance or inductance, and it was by ...

Capacitor Voltage Transformers (CVTs) are central to modern power systems, where they not only scale high transmission voltages into measurable signals but also ensure the precision needed for ...

Occasionally a design requires capacitors that are much closer to being identical in value to one another than the usual ...
