Multivibrator: Circuits, Types and Application08 September 2020
A multivibrator uses deep positive feedback, to turn on and off two electronic devices alternately through the resistance-capacitance coupling, thereby self-excites and generates a square wave output. It's often used as a square wave generator...
What is a Variable Resistor?26 April 2025
With a variable resistor, you can readily adjust the resistance, and therefore the current, of a circuit for functions such as dimming lights, controlling the speed of a motor, or adjusting a signal generator. This article will explain the symbols, construction and types of variable resistors and how potentiometers (three-terminal variable resistors) can be used as adjustable voltage dividers.
The Introduction to USB Type-C Pin Signal and PCB Layout03 December 2021
Hello everyone. Welcome to the new post today. USB Type-C is a smaller-volume USB interface standard than Type-A and Type-B. It can be used on a PC (master device) as well as external devices (slave devices, such as mobile phones).
Introduction to DDIC (Display Driver IC)17 February 2022
Driver IC is an integrated circuit chip that controls the switching and display method of LCD panels and AMOLED panels. With the increase of panel display resolution and data transmission speed, the requirements for driver ICs are also increasing.
What is Safety Relay?12 April 2025
Safety relays represent a critical advancement in industrial automation technology, serving as essential components in machine safety systems. Unlike standard relays, safety relays are specifically engineered to provide reliable protection in potentially hazardous environments. This article explores the fundamental aspects of safety relays, including their operational principles, wiring configurations, and proper implementation methods in industrial settings.
Working Principle and Characteristics of Zener diodes20 March 2020
Zener diodes are diodes that act as regulators. By using the reverse breakdown state of the PN junction, the current of the Zener diodes can be changed within a wide range while the voltage is unchanged.
Introduction to buck, boost, and buck-boost converters28 September 2021
A buck converter (buck converter) is a DC-to-DC power converter that lowers the voltage from the source to the load (in drawing a smaller average current).A boost converter or a DC boost chopper is another name for a DC boost converter. A buck-boost converter is a DC-DC converter with an output voltage that can be higher or lower than the input voltage. This article mainly introduces these three converters and their working principles.
Voltage Regulator: Types, Working, and Applications23 February 2021
A voltage regulator is a part of the power supply device that, under all operating conditions, ensures a stable, continuous voltage supply. During power changes and differences in loads, it controls voltage. As well as DC voltages, it will control AC. We will take a closer look at the idea of a voltage regulator and the different forms in this blog, and we will expand on the common voltage regulator ICs and their common implementations!
Thermistor: Characteristics, Classification, Symbol and Applications06 March 2020
Thermistors are a class of sensitive components. They are divided into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC) according to different temperature coefficients.
How to read Resistors Color Code?26 February 2020
We can read the resistance value according to the resistors color code because of the use of four color bands or five color bands or six color bands on the resistors to indicate the resistance value. The color information representing the resistance value can be read at once from any angle.
Microwave Diode: Introduction and Types07 January 2021
Microwave diodes are diodes that work in the microwave frequency band. It is a solid-state microwave device. Microwave band usually refers to the frequency from 300 MHz to 3000 GHz. After the discovery of the point contact diode effect at the end of the 19th century, microwave diodes such as PIN diodes, varactor diodes, and Schottky diode tubes appeared one after another. Microwave diodes have the advantages of small size and high reliability, and are used in microwave oscillation, amplification, frequency conversion, switching, phase shifting and modulation.
