Capacitive-proximity sensors have been used widely in industrial applications such as counting products on a conveyor, detecting position of valves, presence of objects etc. In recent years, the use ...

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...

Electrical capacitance sensors detect and measure capacitance, which is the ability to store an electrical charge. Capacitive sensors are essentially oscillators, which open a capacitor that generates ...

Editor’s note: I am delighted to bring you part 2 of a two-part tutorial on Integrated Capacitive PGAs in ADCs by our two guest bloggers Miguel Usach and Gerard Mora-Puchalt, from Analog Devices, Inc.

Electrochemical capacitors, also called supercapacitors, store energy using either ion adsorption (electrochemical double layer capacitors) or fast surface redox reactions (pseudo-capacitors). They ...
