LC-tank circuit portion Varactor (or “varicap”) diodes are used primarily in radio-frequency (RF) circuits to provide a capacitance that can be varied by changing the applied voltage.

Diodes, one-way current conductors, are used for voltage regulation, AC/DC conversion, and circuit protection. Forward-biased at 0.6V, conduct current, reverse bias blocks it.

SiC JFETs are extremely robust transistors. Examples include the depletion-mode trench JFETs developed by UnitedSiC, which have no built-in body diode. Combining a SiC JFET with a low-voltage ...

Just to make visualization easy, let's look at a half-wave rectifier circuit. For our first case, we have an ideal diode with zero storage charge and as you would imagine, there is no reverse current ...

Researchers have invented a new organic polymer tunnel diode -- an electronic component that could one day lead to plastic computer memory and plastic logic circuits on computer chips. Today ...

In all cases (single op amp and dual op amp circuits) a diode in the feedback path of the input amplifier curtails its negative-going output voltage swing. Ideally the output of a peak detector ...

Tiny light-emitting diodes with optical microsystems that can produce all the colors of the rainbow, a new method for producing printed circuit boards – Fraunhofer researchers are showing ...
