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.

Figure 3 highlights this parasitic capacitance and the common-mode current used to charge and discharge it. Figure 3 Common-mode current charges the transformer parasitic capacitance when the switch ...

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 ...

Sources of capacitance. Two conductors separated by an insulating material, or dielectric, form a capacitor. Applying an electric charge to the conductors will create an electric field perpendicular ...

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 ...

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.

The airgap reduces the parasitic capacitance between gate and source/drain. The size of the airgap can be controlled by varying the etch depth, tilt and source sigma of the etching reagents. Using ...

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 ...

Depending on the sweep rate of the gate voltage, the net capacitance may increase sharply, then fall as the gate voltage “catches up” and V th is reached. As shown in Figure 3, the change in ...
