XOR gate or Exclusive OR gate is a widely used logic gate in digital electronics. It is one of the logic gates in the Computer which is available in IC form. We discussed basic logic gates like OR gate, AND gate and NOT gate earlier in another article. XOR gate can be constructed using only … Read more
Electricity Transformer is an electrical component that transforms the alternating electric power from one circuit to another circuit with the same frequency of the signal. It can change the amplitude of alternating voltage to a desired value at the output. But the power remains the same both at the primary and secondary coil. In this … Read more
We know that a Transistor can amplify the electric current at its output. Often, the amount of the amplified output does not meet the required criteria. That means we need the output current more than that. Then scientist Darlington proposed a new circuit arrangement with two coupled transistors which provides a huge current gain. This … Read more
Logic gates are the basic building blocks of digital electronics that follow different logical operations. These gates have significant roles in the construction of logical circuits for different computations. Digital electronic devices contain integrated circuits (ICs) which are made of logical gates. In this article, we’re going to explore basic logic gates with truth tables, … Read more
An amplifier can produce an enlarged but exact version of the small input signal at the output of an electronic circuit. Electronic devices like TV, radio, tape recorder, etc. require amplifiers for their operations. These devices do not operate in the same way. Some devices need to amplify the current, some devices require to amplify … Read more
In another article, we have discussed the Bipolar Junction Transistor and the differences between NPN and PNP transistors. Transistor characteristic curve is a very useful thing to understand the basic principle and operation of a Transistor. In this article, we’re going to discuss the input and output characteristics of a Transistor. The main discussion is … Read more
Bipolar Junction Transistor (BJT) is one of the very important electronic circuit components in the world of electronics. Scientist William Shockley discovered the first Transistor in 1948. Modern technology is very much progressive and many varieties of transistors have been discovered. These transistors are widely used in analog and digital electronics. In short, semiconductor diodes … Read more
Transistor is one of the basic circuit components for electronic devices. The main purpose of a Transistor is to Amplify electronic signals. There are two types of BJT Transistors – NPN and PNP. In another article, we discussed the construction, symbol and other properties of BJT Transistors. In this article, we’re going to discuss the … Read more
In the first two articles, we learned the basic things about semiconductor materials. Now, we have entered into the applications of Semiconductors. Semiconductor materials are used to develop many electronic devices. A p-n junction diode is one of those. In this article, I’m going to discuss the formation, characteristics curves, depletion layer, potential barrier, bias … Read more
We already discussed the Semiconductor material and a semiconductor device p-n junction diode. From the latter one, we became to know that a normal P-N junction diode cannot operate at high reverse bias voltage because of the breakdown in diodes. To operate at high reverse bias voltage, a diode is to be designed in a … Read more
