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 ...

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 ...

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.
