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.
An Overview of Crystal Oscillator21 September 2020
The oscillator is an energy conversion device that converts DC power into AC power with a certain frequency, and the circuit formed by it is called an oscillating circuit. Some electronic devices require an AC signal with a highly stable frequency, but the LC oscillator has poor stability and the frequency is easy to drift. A special component-quartz crystal is used in the oscillator, which can generate a highly stable signal. This kind of oscillator using a quartz crystal is called a crystal oscillator.
Introduction to Inductive Reactance16 April 2021
Alternating current can also pass through the coil, but the inductance of the coil has an obstructive effect on the alternating current. This obstruction is called inductive reactance.
NOR Flash: Working, Structure and Applications18 November 2021
NOR flash was first developed by Intel in 1988, and after so many years of development, it is widely used in various computers and embedded products. NOR and NAND is the two main types of non-volatile memory in the market today.
What are the Testing Method and Types of Transistors?21 October 2025
A transistor is a semiconductor device that is commonly used in amplifiers or electronically controlled switches. It’s the basic building block that regulates the operation of computers, cell phones, and all other modern electronic circuits. Due to the fast response time and high accuracy, transistors can be used for a variety of digital and analog functions, including amplification, switching, voltage regulation, signal modulation, and oscillators.
Introduction to the Types of SDRAM13 July 2021
SDRAM (synchronous dynamic random-access memory) is a dynamic random-access memory (DRAM) with a synchronous interface.SDRAM is widely used in computer and electronic devices.
AC/DC, DC/DC Converter Fundamental Guide04 June 2026
Hello everyone, I am Rose. Welcome to the new post today. This article mainly introduce the definition of AC and DC, AC/DC Converter as well as DC/DC converter.
Power Management Integrated Circuit (PMIC) Guide10 February 2022
Power Management Integrated Circuits (PMIC) is a chip that is responsible for the conversion, distribution, detection and other power management of electrical energy in electronic equipment systems.
Near Field Communication (NFC) Explained: Working and Applications24 May 2021
Near Field Communication (NFC) is evolved from the integration of non-contact radio frequency identification (RFID) and interconnection technology. Devices using NFC technology can exchange data when they are close to each other. By integrating the functions of inductive card readers, inductive cards, and point-to-point communication on a single chip, applications such as mobile payment, e-ticketing, access control, mobile identification, and anti-counterfeiting can be realized by using mobile terminals.
General PCB Layout Design Guidelines for RF and Digital-to-Analog Circuits20 January 2022
This article provides guidance and advice on radio frequency (RF) printed circuit board (PCB) design and layout, including some discussion of mixed-signal applications such as digital, analog, and RF components on the same PCB. The content is organized by topic to provide "best practice" guidelines that should be applied in conjunction with all other design and manufacturing guidelines that may apply to specific components, PCB manufacturers, and materials.
Image Sensor: How do CCD and CMOS Sensors work?24 October 2025
An image sensor is a semiconductor device that can convert optical images into digital signals. It is widely used in digital cameras and other electronic optical devices. The image sensor uses the photoelectric conversion function of the photoelectric device to convert the light image on the photosensitive surface into an electrical signal in a proportional relationship with the light image. There are two kinds of image sensors which are CMOS and CCD. CCD and CMOS have their advantages in different application scenarios.
Basic Introduction to Color Sensor07 January 2026
The color sensor is also called a color recognition sensor. It is a sensor that compares the object color with the previously taught reference color to detect the color.
