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 ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

Raising energy density bars, the company’s latest cylindrical lithium ion capacitor (LIC) expands energy capacitance up to ten times greater than conventional electric dual layer capacitors (EDLCs).

According to precedence, MOSFET datasheets show output capacitance at a single measured voltage. While these values were good enough for relative comparison between products in the past, it is ...

Electrochemical capacitors, also called supercapacitors, store energy using either ion adsorption (electrochemical double layer capacitors) or fast surface redox reactions (pseudo-capacitors). They ...

Taiyo Yuden's new Cylindrical Lithium Ion Capacitor (LIC) offers extremely large energy capacitance and high reliability. Combining the strength of lithium-ion secondary batteries with conventional ...

There are many parameters to consider when designing a circuit using an operational amplifier (op amp) including the op-amp’s gain bandwidth (GBW) product, offset voltage and quiescent current. In ...
