Most designers know that dc bias significantly decreases the effective capacitance of Class II MLCCs. But is it enough to estimate the effective capacitance of an MLCC just by ...

Note that the Y-caps in a DC-DC converter are always between two DC levels, so we can forget ground leakage currents and their related safety issues. Therefore there is more flexibility in choosing ...

Variable current will generate inductance, capacitance, and their related properties of inductive and capacitive reactance. Although there's no energy loss that directly results from these properties, ...

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 capacitance meter generates two signals; one of them lags the other by 60°. A 3-bit, self-correcting, divide-by-six twisted-ring counter comprising IC 6 , IC 7 , and IC 13B provides the lagging ...

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.

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 ...

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 ...

Energy saving: artist’s impression of the gate material with negative capacitance. (Courtesy: Ella Maru Studio) By exploiting a curious effect called negative capacitance, researchers have designed a ...
