Since capacitance is inversely proportional to frequency, given a fixed measurement time, the schemes naturally provide the highest bit resolution for the lowest capacitance values in a given range.
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 ...
This says that ALL 50 Ohm transmission lines in FR4 have exactly the same capacitance per length. If we make the line width wider, we have to make the dielectric thicker to preserve the 50 Ohms, and ...
That said, measuring capacitance against a voltage isn’t something any ‘ol meter can do, and we’re glad [limpkin] could put together an easy to use tool that measures this phenomenon.

Negative capacitance arises in ferroelectric materials, whose spontaneous electric polarization can be reoriented with the application of an external electric field. To create negative capacitance, an ...
The negative capacitance is a direct result of the intrinsic energy barrier between two stable polarization states of the ferroelectric layer, he says. In regular ferroelectric capacitors with two ...
Many techs shut systems down, discharge the capacitors, remove the leads, and test with capacitance testers on their multimeters. There are situations when this makes sense, such as when the system is ...
