What is an Integrated Circuit (ICs) and Why Integrated Circuit is shortage?23 September 2021
An Integrated Circuit(IC), or we can call it IC, chip, or microchip is a small semiconductor-based electronic device minuscule chip consisting of fabricated transistors, resistors, and capacitors, and other metallic connections required for a complete electrical circuit. In this article, we will discuss it in five aspects.
What is Amplifier?08 November 2025
Hello everyone, I am Rose. Today I want to introduce amplifier to you. An amplifier is a device that can amplify the voltage or power of an input signal, and is composed of tubes or transistors, power transformers and other electrical components. Used in communication, broadcasting, radar, television, automatic control and other devices.

What is a Schmitt Trigger?09 December 2021
Schmitt triggers have two stable states, but unlike general triggers, Schmitt triggers use a potential trigger mode, and their state is maintained by the input signal potential. Schmitt triggers have different threshold voltages for input signals with two different changing directions, negatively decreasing and positively increasing.
What are Shunts?07 December 2020
A shunt is a measuring element that uses voltage to indicate current. It is made according to the principle of generating voltage at both ends of the resistor when DC current passes through the resistor. It is connected in parallel with the current circuit of measuring instruments to expand its measurement range; or An element on which voltage is measured, thereby indirectly measuring current.
