Can an LED be used as a photodiode?

In most circuits, you can replace a standard silicon photodiode with an LED. Pay attention to the polarity. Also keep in mind that the LED is not as sensitive as…

How does photodiode detect light?

LEDs can also be used as photodiodes because they can emit and sense light from their junction. All PN junctions are photosensitive and can be used in a photoconductive, undistorted…

What is meant by avalanche photodiode?

An avalanche photodiode (APD) is a highly sensitive electronic semiconductor device that utilizes the photoelectric effect to convert light into electricity. High sensitivity and low noise, Fast reaction and Low-light…

What is Zener breakdown?

The Zener diode is a PN junction diode that was specially developed for operation in the blocking mode. In the forward bias mode, it acts as a normal diode. It has a…

Can waves be accelerated?

Yes,  wave can accelerate  . The electron matter  wave  in the atom is an example of a  wave  that keeps changing its direction. The steady state condition of quantum mechanics, however, requires that such a  wave forms eigenmodes of the…
