Here are a number of alternative ways to avoid problems when driving Varactor Diodes. Varactor (or “varicap”) diodes are used primarily in radio-frequency (RF) circuits to provide a ...

If the power supply does not have embedded short circuit protection ... the clamping levels associated with reverse polarity. Power dissipation during the reverse-bias condition is a major ...

Save guides, add subjects and pick up where you left off with your BBC account. Circuit symbol: the diode symbol consists of a triangle pointing towards a line. The triangle represents the anode ...

where the gradual smooth change into reverse bias takes much longer than the diode's Trr. But you can see that in abrupt switch mode operation, the diode becomes a virtual short circuit for a large ...

Here is a detailed view of reverse polarity protection circuits for safeguarding battery-connected automotive systems.

There is another family of transistors which have analogous circuit ... diode with two cathode terminals. If however you give the gate a negative bias compared to the source, the diode becomes ...

The base forms the input and its bias circuit is identical to that of the ... the base-emitter junction of a transistor is also a diode, it will always maintain approximately the same voltage ...

As a real-world example (Fig ... and a pair of diodes, each reverse-biased to the bipolar power rails. Such a network often forms part of an overvoltage protection circuit. Any incoming voltage ...
