MOS Selection Rules
 
Introduction:
MOS (Metal Oxide Semiconductor) is a common circuit component widely used in integrated circuits. MOS selection rules refer to a series of rules and methods for selecting appropriate MOSFET models and parameters according to circuit requirements and performance specifications during circuit design. This article will introduce the basic concepts, application scenarios, and specific operational steps of MOS selection rules, helping readers understand and apply MOS selection rules.

In practical applications, the most popular and common electronic components are Bipolar Junction Transistors (BJT) and MOSFETs.

IGBT Physical Diagram + Circuit Symbol Diagram
You can think of IGBT as a fusion of BJT and MOSFET. IGBT has the input characteristics of BJT and the output characteristics of MOSFET.
Compared to BJT or MOSFET, the advantage of Insulated Gate Bipolar Transistor (IGBT) is that it provides greater power gain than standard bipolar transistors, as well as higher operating voltage and lower MOS...

Static electricity from the human body, environment, and even inside electronic devices can cause various damages to delicate semiconductor chips, such as penetrating the thin insulating layer inside components; damaging the gates of MOSFET and CMOS components; latch-up in CMOS devices; short-circuiting reverse-biased PN junctions; short-circuiting forward-biased PN junctions; melting bonding wires or aluminum wires inside active devices. To eliminate the interference and damage caused by electrostatic discharge (ESD) to electronic devices, various technical means need to be taken for prevention.

Not only for EVs and hybrid vehicles, but also for pure fuel vehicles, semiconductors are essential components. This is a fact that people have witnessed.

Take recent clean diesel vehicles (Clean Diesel Vehicle) as an example, their mode is as follows: each combustion cycle injects fuel about five times, effectively using fuel, extracting torque, although fuel consumption increases, but can discharge clean gas as much as possible.

Power semiconductor devices refer to electronic devices that can directly achieve electrical energy conversion or circuit control in main circuits, mainly used for power conversion, including rectification, inversion, DC chopping, as well as AC power control, frequency conversion, or phase change. Unlike other types of semiconductors, power semiconductors can withstand high voltage and large current, usually operating in switching state, and are the core of electrical energy conversion and circuit control, playing a key role in efficient generation, transmission, conversion, storage, and control of electrical energy.
Power semiconductor devices can be divided into bipolar power semiconductors and unipolar power semiconductor devices according to carrier type. Bipolar power semiconductor devices include...

What is a Semiconductor?









        "Semiconductor" is a substance whose characteristics are between "conductor" and "insulator", the former conducting electricity like metal, the latter almost not conducting electricity. The ease of current flow is related to the electrical...

Silicon wafers are the infrastructure of China's "core" and one of the cornerstones of China's new infrastructure.
In the semiconductor industry chain, silicon wafers, as an important core material in chip manufacturing, play a key role in chip manufacturing. The quality, size, cost, etc., of silicon wafers directly affect chip performance and competitiveness.
At the historical intersection point of China's economic transformation cycle and global technological innovation cycle overlapping, China's semiconductor silicon wafer market has become the fastest-growing market globally. According to SEMI (International Semiconductor Industry Association) statistics, China's semiconductor silicon wafer sales reached 16...

We often see a small cylindrical bulge on data cables or power cables of laptops, digital cameras, etc., which actually contains a ferrite magnetic ring clamp filter. This is the result of electromagnetic compatibility anechoic chamber testing.
　　 If noise reduction is handled well during electronic product development, this filter is not needed. However, if the product itself has been developed and problems are still found during testing, the simplest method is to add a filter. One reason is that during data transmission, cables also radiate electromagnetic waves.
　　
　　 The demand for anechoic chambers is growing year by year
