What is capacitor and its unit?

A capacitor is a passive electrical component with two terminals that stores electrical energy in an electric field. The effect of a capacitor is known as capacity. While there is…

How does avalanche photodiode work?

An avalanche diode is a special type of semiconductor device designed to operate in the reverse breakdown mode. Avalanche diodes are used as over pressure valves (a type of valve…

Why do photodiodes operate in reverse bias?

Photodiodes more effectively convert incident light into electrical current in the off-state than in the off-state, as the width of the stopband increases as you increase the blocking voltage –…

What are the applications of photodiode?

The photodiode is widely use in day to day life means in consumer electronics and in industry. Application of photodiodes. The photodiode is used in an optical communication system. The…

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…
