Engineers usually have access to signal and function generators, as well as frequency counters and oscilloscopes, but they may not have access to capacitance or inductance meters. Using the test setup ...

A recently filed patent (Publication Number: US20230314495A1) describes a capacitance measurement circuit that includes an analog front-end circuit, a parasitic capacitor, an analog to digital ...

An old Electronics Designer’s Casebook described a circuit that provided capacitance measurements of 10 pF to 1 µF with 1% accuracy (Reference 1). A number of issues emerged with the circuit during ...

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 ...

Nanusens has designed an all-digital capacitance measurement circuit to integrate alongside its MEMS sensors. “This means that both the sensor structure and its detection circuitry can be made at the ...

Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...

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 ...

Capacitance-voltage (C-V) testing is widely used to determine semiconductor parameters, particularly in MOSCAP and MOSFET structures. However, other types of semiconductor devices and technologies ...

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 ...
