Were you to bias an n-channel JFET as you would a bipolar transistor with a positive bias on its gate, the diode between gate and source would conduct, and the transistor would remain a diode with ...

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.

At positive bias (or reverse bias), when the diode blocks the current, this HOMO level falls below both Fermi levels and cannot participate in the mechanism of charge transport.

This protection generally includes internal clamp diodes to the supply rails. The OPA320 is an example in figure 1a. ... Of course, the opposite occurs as the input approaches the positive supply rail ...

The diode transmits terahertz waves when biased with a positive voltage while attenuates the wave under a low negative voltage, which can be seen as an analogue of an electronic semiconductor diode.

The test setup was easy: Drive the diode-under-test (DUT) with a 5V pulse – DC offset set mostly negative to bias the diode on only during positive peaks. Scope both sides of the DUT and trigger on ...

When transistor Q2 is turned on, a positive V in potential is applied to the non-dot end of the N2 winding. During the time Q2 is conducting, diode D2 will be forward biased and provide power to ...
