Op amps with low input capacitance are required in applications such as smoke detectors, photodiode transimpedance amplifiers, medical instrumentation, industrial control systems, and the piezo-sensor ...

Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

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 ...

Electromechanical switches are simple, cheap, and widely available (Fig. 1). However, they’re also plagued with a number of disadvantages, including wear with repeated use, and the potential for ...

The capacitance of a classical conductor is determined solely by its geometry. When charged, the electrons distribute in space in a manner that minimizes their electrostatic energy. Quantum mechanics ...

During the manufacture of semiconductor wafers, thickness measurement forms an important part of this process, since it provides process engineers with the information required to ensure that ...
