LED or Light Emitting Diodes: Definitive Basic Guide
A light emitting diode or LED is a PN semiconductor device. The PN Junction produces light when electric current passes through it.
A light emitting diode or LED is a PN semiconductor device. The PN Junction produces light when electric current passes through it.
What is a Gunn diode A Gunn Diode is a microwave semiconductor diode designed to work in devices having microwave frequencies. Microwave Frequencies are electromagnetic radiation of tremendously high frequencies (THF), (maximum working frequency up to 3 THz, this depends on the material used in its structure). The most common materials used in their manufacturing…
Every student faces difficulty understanding the concept of Tunneling effect in the tunnel diode. Students are much confused about different types of diodes they encounter in their academics. We have already explained Photodiodes, Zener diode, Schottky Diode, LED etc. Now, we are going to explain about Tunnel diode, working operation, construction, and applications etc. What is…
Schottky diode is also known as the hot carrier diode is made up of semiconductor-metal junction rather than a p-n semiconductor junction. It is widely used for radio frequency, RF applications as a mixer or detector diode. In our previous articles, we explain about Zener Diode, Light emitting diode, Photodiode etc. In this article, we…
Photodiode operation is based on a mechanism known as the photoelectric effect, which creates electron-hole pair when a photon of sufficient energy strikes the diode.
Zener diode is a special kind of diode which permits the flow of current in the forward direction as well as in reverse direction when the voltage is above a certain voltage known as breakdown or Zener voltage. In our previous articles, we explain in detail about diodes, PN junction diode, semiconductors etc. In this…
Diode is an electronic device conduct current in one direction i.e. either in the forward direction or in the reverse direction. Today’s most commonly used diode is semiconductor diode. In our previous articles, we explain basic theory of semiconductors, P-n junction diode, and P-n junction diode characteristics etc. Here we are going to explain about Diodes…
Pn junction diode is one of the most basic diodes. It is used in the construction of transistors, FET, Gates and many other types of integrated circuits. These are the easiest and basic diodes available in and use PN junction characteristics like depletion layer, diffusion and drift current. We prefer to read our article on PN…
We all know how much we struggle to read wiring diagrams properly. And I know you are completely at the “no-fault zone” with this. With many electrical symbols, it is very difficult to remember every one of them and using them while solving a circuit diagram. But there is an easy way to remember them….
In electronics, power amplifiers are categorized into various classes. These classes are based on the different characteristics of different power amplifier circuits. And Class A Amplifier is one of the simplest types of power amplifiers. Though it is least used power amplifier, it is one of the most asked amplifier class in interviews and various…
