What are Avalanche Diodes?02 April 2020
Avalanche diodes are semiconductor devices that use the avalanche multiplication effect and carrier transit time effect in the PN junctions to generate microwave oscillations. If a large reverse voltage is applied across the diode, the space charge region is widened from the N + P junction to the IP + junction. The electric field in the entire space charge region is the largest at N + P. If the electric field intensity exceeds the breakdown electric field in a small area near the N + P junction, then this phenomenon is called avalanche breakdown and the area where it occurs is the avalanche region.
What is LCD? Working Principle, Features, and Future Trends05 January 2026
LCD is a liquid crystal display. The LCD structure is to place a liquid crystal cell between two parallel glass substrates. LCD has replaced CRT as the mainstream, and the price has dropped a lot, and it has become fully popular.
What is a Fixed Inductor?15 April 2021
Fixed inductors are a classification of inductors according to their structure, and fixed inductors are commonly used inductive devices. An inductor with a fixed inductance is called a fixed inductor (or a fixed coil), and it can be a coil with a single layer, multiple layers, honeycomb type, or a magnetic core. These coils are winded on the magnetic core using a wire of corresponded diameter and they are packaged with epoxy resin or plastic according to the inductance and the maximum DC operating current.
AC/DC, DC/DC Converter Fundamental Guide28 February 2022
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.
In-depth Analysis of the Global Semiconductor Supply Chain20 January 2022
The epidemic has led to a sudden surge in demand for digital products and technological advances. The millions of digital devices we use, from smartphones to electric cars, computers, robots, and the businesses they enable, all owe their existence to complex chips built on semiconductors. The global digital economy is estimated to account for up to 22.5% of global GDP.
What is an Oxygen Sensor?24 April 2025
The oxygen sensor is an essential component on engines using three-way catalytic converters to reduce exhaust pollution. It uses ceramic sensitive elements to measure the oxygen potential in the exhaust duct of the car. There are two kinds of oxygen sensors in practical application: zirconia oxygen sensor and titania oxygen sensor.
Car Sensors: Classification and Application27 October 2025
The car sensor is the input device of the automotive computer-controlled system. The earliest car sensors are oil pressure sensors, oil quantity sensors, and water temperature sensors connected to instruments or indicator lights in the 1960s. There are many kinds of car sensors like temperature sensors, pressure sensors, flow sensors, etc., and they are applied in different applications according to their specific properties.
Top 10 Popular Semiconductor Companies in 202525 December 2025
The semiconductor industry is made up of businesses that design and manufacture semiconductors and semiconductor devices like transistors and integrated circuits. It was founded around 1960, when semiconductor device manufacture became a viable enterprise. Since then, the industry's yearly semiconductor sales revenue has risen to more over $481 billion in 2018. This article presents the top 10 most popular semiconductor companies in 2022.
Types, Structure, and Packages of Integrated Circuits23 October 2025
The type of integrated circuit can be divided according to its use, function, structure, manufacturing process, integration, and conductivity type. The structure of the integrated circuit can be learned from levels from top to bottom: system level - module level - register transfer level (RTL) - gate level - transistor level. The packaging forms of integrated circuits include SOP, PGA, BGA, DIP.
What is Digital Counter?01 September 2020
Counting is one of the simplest basic operations. In digital logic and computing, the counter is the logic circuit that realizes this kind of operation. In the digital system, the counter mainly counts the number of pulses to realize the functions of measurement, counting, and control.
An Overview of Thermal Overload Relays12 October 2020
Thermal overload relays are protective electrical appliances used for overload protection of motors or other electrical equipment and electrical circuits, The thermal overload relay is mainly used for overload protection of asynchronous motors. After the overload current passes through the thermal element, the bimetallic sheet is heated and bent to push the action mechanism to drive the contact...
