Conductivity of Semiconductor materials

Earlier we have discussed the basic properties, examples, types and applications of semiconductor materials. We became to know that semiconductors are not excellent conductors of electricity at room temperature. That means a pure semiconductor is not suitable for conducting current and hence it cannot be used to design electronic devices. But there is a solution. … Read more

Semiconductor – Properties, examples and applications

Modern Technology is based on Semiconductors. The discovery of semiconductors has given a new direction to Science and Technology. You can access online articles from your home, institution and anywhere because of the invention of semiconductor materials. In this article, I’m going to explain what is a semiconductor and what are its properties and applications. … Read more

Types of Breakdown in diode and their causes

A p-n junction diode works properly in forward bias condition. Because a higher amount of current flows for this biasing condition. On the other hand, a very small amount of current flows through the diode when it is connected to a reverse bias. Again, a higher amount of reverse bias voltage can create a breakdown … Read more

Advantages and Disadvantages of Solar Energy

Solar energy is a trending topic of science in recent times. The non-renewable sources of energy are about to extinct due to their limited storage on the Earth. Therefore, alternative sources of energy are needed to fulfill our daily needs of energy. There are some renewable sources of energy like Solar energy, Wind energy, Geothermal … Read more

OR AND & NOT gates using universal NAND gate

Basic logic gates like OR gate, AND gate and NOT gate are already discuused in another article. Again, we know that universal logic gates like NAND gate and NOR gate can be used to implement all other logic gates including XOR gate and XNOR gate. This article shows the Implemention methods of OR gate, AND … Read more

XNOR gate using NAND & NOR gate

XNOR gate is one of the logic gates available in integrated circuit (IC) form. Its full name is Exclusive NOR gate. It is different from Basic logic gates (OR gate, AND gate and NOT gate) and universal logic gates (NAND gate and NOR gate). In this article, we are going to discuss the logic circuit … Read more

Karnaugh map for simplification of Boolean expression

Karnaugh map is a very useful tool for simplification of Boolean expression in digital electronics. The other name of Karnaugh map is K-map or K map. It can be used to represent the Boolean equation both in sum of products (SOP) form and product of sum (POS) form. There are two ways to simplify Boolean … Read more

Rules of Boolean algebra for simplification

Boolean algebra is the mathematical reasoning for simplification of binary expressions. It is completely different from the conventional general algebra. Boolean algebra deals with the binary bits only which is the arithmatic method of computers. There are different laws of Boolean algebra that are used to simplify Boolean expressions. In this article, we are going … Read more

NOR gate truth table and circuit diagram with 3 inputs

NOR gate is one of the universal logic gates other than NAND gate. NOR gate contains an OR gate and a NOT gate in series.This suggests that a NOR gate can give the inverted output of an OR gate. In this article, we are going to discuss the circuit diagram, Boolean expression and truth table … Read more

NAND Gate Truth Table and Circuit diagram with 3 inputs

NAND gate is the most important logic gate in digital electronics and integrated circuits. IC7400 is a popular IC that consists of 4 NAND gates. The biggest importance of NAND gate is that it is one of the universal logic gates using which other logic gates can be implemented. Construction of basic logic gates using … Read more
