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.
What is AMOLED?25 April 2021
AMOLED is an active-matrix organic light-emitting diode. AMOLED is a display technology for mobile devices, digital cameras, media players, and television. It uses active matrices to address pixels and uses a special type of film technology, wherein the organic compound forms an electroluminescent material.
An Overview of Digital Signal Processor31 October 2025
A digital signal processor (DSP) is a processor composed of large-scale integrated circuit chips to complete digital signal processing tasks. Digital signal processing is the theory and technology of representing and digitally processing signals. Digital signal processing and analog signal processing are a subset of signal processing.
What is a Capacitive Sensor?31 October 2025
Capacitive sensors use various types of capacitors as sensing elements. It is a conversion device that converts the measured physical or mechanical quantities into changes in capacitance which is actually a capacitor with variable parameters. Capacitive sensors are widely used for measurement of displacement, angle, vibration, speed, pressure, composition analysis, medium characteristics, etc.
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
What is inductor: Symbol, Applications and Types04 January 2022
As we begin our studies in 2022, we will work together to decode inductance today. What is an inductor? What enables it to work normally? The answer is the existence of this induced current.
Stepper Motor: Types, Working and Applications26 December 2025
A brushless, synchronous electric motor that converts digital pulses to mechanical shaft rotation is known as a stepper motor. When operated by a sequentially switched DC power supply, the normal shaft motion is made up of discrete angular motions of approximately uniform magnitude.
800G Optical Transceivers: The Guide for AI Data Centers24 December 2025

Introduction to Mass Air Flow Sensor15 September 2020
Mass air flow sensor is one of the important sensors of EFI engines. It converts the inhaled air flow into an electric signal and sends it to the electronic control unit (ECU). As one of the basic signals for determining fuel injection, it is a sensor that measures the air flow into the engine.
What are Types and Application of Gas Sensors?18 November 2025
The gas sensor is the core of the gas detection system and is usually installed in the detection head. Essentially, a gas sensor is a converter that converts a certain gas volume fraction into a corresponding electrical signal. The probe uses the gas sensor to adjust the gas sample, which usually includes filtering out impurities and interfering gases, drying or refrigeration treatment, sample pump, and even chemical treatment of the sample, so that the chemical sensor can make faster measurements. In the following, we’ll mainly discuss the properties, typical types and application fields of gas sensors.
Basic Introduction to the Types of Capacitors16 October 2025
A variety of capacitors are used in the manufacture of electronic devices, and they play different roles in the circuit. There are many types of capacitors, such as fixed capacitors, variable capacitors, and trimmer capacitors, and fixed capacitors can be divided into ceramics, mica, paper, film, and electrolytic capacitors according to the different dielectric.
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.
