Audio Transformer-Types, Functions and Working05 January 2026
An audio transformer is an electromagnetic system designed to separate an input circuit from an output circuit and produce a signal that passes through it with filtering. A varying electromotive force (voltage) in the secondary winding linked to the other circuit is caused by this changing flux.
How to make an Obstacle Avoiding Robot?29 August 2023
The article will tell you How to make an Obstacle Avoiding Robot.
Analog Switch: Types and Application25 March 2021
The analog switch is mainly to complete the signal switching function in the signal chain. The switching mode of the MOS tube is adopted to realize the switching off or on of the signal link.
What is a Cascode Amplifier?27 March 2025
An analog circuit's output is increased by using a cascode amplifier. The use of cascode is a common approach that can be extended to both transistor and vacuum tube applications. In the year 1939, the tern cascode was included in an article written by Roger Wayne Hickman and Frederick Vinton Hunt.
An Overview of Common Mode Chokes10 August 2020
Common mode chokes are often used in computer switching power supplies to filter common mode electromagnetic interference signals. This article helps you learn about the Features, Working Principle, Selection Method, Precautions, and Core Material of common mode chokes. Click for more.
800G Optical Transceivers: The Guide for AI Data Centers21 August 2026
The complete guide to 800G Optical Transceiver standards (QSFP-DD vs. OSFP). Overcome supply shortages and scale your AI data center with Utmel Electronic.
Diode Basis: Symbol, Types and Applications09 January 2026
Hello everyone, I am Rose. Today I will introduce diode to you. A diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). It has unidirectional conductivity, that is, when a forward voltage is applied to the anode and cathode of the diode, the diode conducts. When a reverse voltage is applied to the anode and cathode, the diode is turned off.
How do Transistors Work?10 August 2020
A transistor is a kind of semiconductor device that controls current. Its function is to amplify the weak signal into an electrical signal with a larger amplitude value, and it is also used as a contactless switch.
What is Electronic Ballast?28 September 2020
Electronic Ballast is a kind of ballast, which uses electronic technology to drive the electric light source to produce the required lighting. Corresponding to it is the inductive ballast. More and more modern fluorescent lamps use electronic ballasts, which are light and compact, and people can even integrate electronic ballasts with lamps.
Introduction to Photonic Integrated Circuits and PIC Technology22 October 2025
The concept of the photonic integrated circuit is similar to the concept of electronic integrated circuits. However, electronic integrated circuits integrate transistors, capacitors, resistors, and other electronic devices, while PIC integrates various optical devices or optoelectronic devices, such as lasers, electro-optical modulators, photodetectors, optical attenuators, optical multiplexers/demultiplexers, and optical amplifiers.
What is Regulated Power Supply?08 January 2021
Regulated power supply is an electronic device that can provide stable AC or DC power to the load, including AC regulated power supply and DC regulated power supply.
Introduction to Servo System08 September 2021
Servo system is a product developed on the basis of frequency conversion technology. It is an automatic control system that takes a mechanical position or angle as the control object.
