Ideal capacitors only exist in textbooks. Every real-world capacitor has additional complexity arising from its physical structure. Two plates separated by a dielectric layer are in series with wire ...

Norwood, Mass. — Analog Devices, Inc.'s new families of capacitance-to-digital converters (CDCs) and impedance-to-digital converters (IDCs) simplify instrumentation and sensor design in industrial, ...

Paul Whytock reports on integrated converters that tackle the signal-processing challenges of direct capacitance-to-digital and impedance-to-digital conversion. The world's first high-precision, ...

Any grizzled electronic engineer will tell you that RF work is hard. Maintaining impedance matching may be a case of cutting wires to length at lower frequencies, but into the low centimetre and ...

The rules of the National Electrical Code are written for people who have a pre-existing knowledge of electricity. In order to make sense of the Code, you must first understand basic electrical ...

Sigma-delta (SD) A/D converters are widely used in applications featuring sensors with small responsivity and reduced bandwidth, due to the high dynamic range offered by this architecture. SD ...

Known as EIS, Electrochemical impedance spectroscopy is an increasingly common non-destructive technique that is used to analyze and identify a material’s physicochemical properties, especially at the ...
