Researchers have developed a capacitor with a metal-insulator-semiconductor diode structure that is tunable by illumination. The capacitor, which features embedded metal nanoparticles, is similar to a ...

Any PN junction diode can be used as a variable capacitor in reverse biased mode, as well as in the forward biased mode before the knee voltage. The capacitance is usually very small as the junction ...

The integration method was used to build this capacitance meter where it measures the time it takes a capacitor to charge to calculate the capacitance. An Atmel AVR MCU is utilized in this circuit ...

For flyback power supplies that need long holdup times, a technique called on-time extension maintains regulation with less bulk input capacitance than would be required with conventional, ...

(Nanowerk News) A team of researchers at the Israel Institute of Technology has developed a new capacitor with a metal-insulator-semiconductor (MIS) diode structure that is tunable by illumination.
