A capacitor measured with a $100 handheld multi-meter can give a substantially different result than the same capacitor measured with a $10,000 LCR meter. That same capacitor measured with two ...

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 ...

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 ...

An optimal way to determine an op amp's input capacitance. Steps involved in making the input-capacitance measurement. 1. With a series resistor at the op-amp input, the input capacitance of the op ...

This paper defines a method to measure the chip die pad capacitance using time delay reflectometry (TDR). This method is useful for measuring the low-value capacitance that is present at the end of a ...

Have you ever found the need to measure the capacitance of a capacitor? No multimeter handy (for shame)? Well, as it turns out you can actually measure capacitance using your Arduino Uno, with no ...

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 ...

Capacitive displacement sensors span a wide range of resolution, from the touchscreen sensors which can only detect displacement as a binary state, all the way to the sensors in semiconductor fabs ...

If you’re the person tasked with controlling the level of fly ash in collection hoppers, you know how difficult the application can be. What at first looks like a simple measurement quickly proves to ...
