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, ...

In the “Say It with Me” series, we’ll take a commonly used concept out of electronics and explain it the best we can. If there’s something that’s been bugging you, or a certain term or concept that ...

Capacitive sensing has emerged as a promising non-contact approach for acquiring biopotential signals such as electrocardiograms and electrodermal activity. Unlike conventional methods that rely on ...

In most power-supply design examples it is common to arbitrarily place the crossover frequency at one-fifth or one-tenth the switching frequency. However, the crossover frequency actually affects the ...

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 ...
