Network Interface Card: Types, Functions and Buying Guide17 August 2021
Network Interface Card (NIC, also known as a network interface controller) is one of the most basic components in the local area network. It is the hardware device connecting the computer and the network. Whether it is a twisted pair connection, a coaxial cable connection, or an optical fiber connection, data communication must be realized with the help of a network interface card.
An Overview of Supercapacitors03 March 2020
Supercapacitors, also known as electrochemical capacitors, electric double-layer capacitors, gold capacitors, and farad capacitors, are developed between the 1970s and 1980s, which is an electrochemical element that uses polarized electrolytes to store energy. The supercapacitor is different from the traditional chemical power supply. It is a power supply with special performance between the traditional capacitor and battery, which mainly relies on the electric double layer and redox pseudo capacitor charge to store electrical energy. However, no chemical reaction occurs during the energy storage process. This energy storage process is reversible, for which supercapacitors can be repeatedly charged and discharged hundreds of thousands of times.
Wireless Charging Explained: Working and Standards26 May 2021
Wireless charging technology originates from wireless power transmission technology, which can be divided into low-power wireless charging and high-power wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method for charging mobile phones. High-power wireless charging often uses resonance (most electric vehicle charging uses this method) from the power supply equipment (charger) to transfer energy to the device that uses electricity.
Hall Effect: Definition, Principle, Measurement Methods08 November 2022

An Overview of JFET19 August 2020
JFET is a Junction field-effect transistor. Regular transistor is a current-controlled device that requires biasing power, while JFET is a voltage-controlled device. The JFET is an active electronic component that is one of the electronics industry's workhorses that offers a reasonable compromise between cost and efficiency.
How to Understand the Oscilloscope Bandwidth?13 December 2021
When a user selects an oscilloscope for essential measurements, the oscilloscope's key characteristics are frequently the only criteria used to determine which oscilloscope to employ. An oscilloscope's most essential index parameters are:Bandwidth, Sampling Rate, Record length
A Guide to Semiconductor IP Core18 January 2022
The IP to be introduced in this article is both a technical term and a commodity. It brings together the wisdom of chip designers and has the attributes of a commodity and intellectual property, which can be promoted, sold, and applied. Therefore, there are scientific and commercial activities such as IP development, IP trading and IP reuse in the semiconductor industry, and there are also some companies that are named as IP vendors and IP providers.
Introduction to Temperature Sensors22 May 2020
The temperature sensor refers to a sensor that can sense the temperature and convert it into a usable output signal, which is the core part of the temperature measuring instrument. It's divided into 5 types and each type has unique working principles. Besides, some factors need to be noticed in the installation and using process. For the temperature sensor can accurately measure the ambient temperature, it's widely used in various fields and provide convenience for people's production and daily lives.
