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 ...

The electron transport properties of graphene devices are critical to many applications, but our understanding of these properties is still incomplete, in spite of rapid advances in recent years. One ...

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 ...

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 ...

We discussed in the previous tutorials the dielectric—the insulating material that prevents the two parallel conductive plates from touching each other. An electrical current flows when a voltage is ...

Existing test solutions aren’t always suitable for the latest improvements in switching regulator technology. Transient load testing can address these inequities. In response to the recent ...
