Half Adder
Half Adder An adder is a logic circuit that can perform additional operations on binary numbers. It can be composed of only three types of logic circuits: AND, OR, and NOT gates.…

Semiconductor Simulation
Logic Gate
Logic Gate Logic circuits are responsible for arithmetic operations in a computer. All numbers are converted to binary for the logic circuit to work. A binary number is a number system that…

Transistor application circuit
The above simulation is based on a circuit that actually works. The transistor uses C1815(general-purpose NPN switching transistor). The resistance connected to the base is 100kΩ, and the resistance connected to the…

Rectifier Circuit
Diode Diodes are electronic components that pass current in only one direction. The direction in which current can flow through the diode is called ‘forward,’ and the direction in which current cannot…

The principle of LED
LED LEDs are electronic devices that emit photons. LEDs have higher efficiency and longer life than bulbs. Basically, LEDs have a structure like a p-n junction diode. The p-n junction diode is…

The principle of a transistor
Transistor There are so many switches inside your computer that you can’t imagine. It’s not the hand-pressed switch we’ve been seeing. It is a switch operated by an electrical signal. The computer…

Energy Band of Metal
Energy band and band gap of atom According to Niels Bohr’s atomic model, electrons subordinate to an atomic nucleus do not have continuous energy. Electrons can only have sparsely defined energies. This…

Diode making
A diode is an electronic component that conducts current primarily in one direction. It has low resistance in one direction, and high resistance in the other. A diode is made by joining…
