Firstly, divide the area according to the functional units of the circuit, and consider all the components of the circuit as a whole. Divide each functional circuit unit into a general area according to the module, making the layout suitable for signal flow and maintaining consistent direction as much as possible.

Chip manufacturers are cautious about the trade war, and if negotiations with China are successful, they won't fight anymore?

How to choose resistors in circuit design?

Sep 24,2024

Resistors are one of the most commonly used components in electronic products, and basically any electronic product will have resistors inside. Resistors can be used as voltage dividers, splitters, and load resistors in circuits; It can form filters and delay circuits together with capacitors; Used as a sampling resistor in power or control circuits; Used as a bias resistor in semiconductor tube circuits to determine the operating point; Using resistors with special properties such as varistors and thermistors to prevent surge voltage, suppress surge current, and achieve over temperature protection, etc. Resistors are the most common and indispensable components in circuits. Choosing and using resistors well is crucial for the stable operation and reliability of products.

The Development History of Resistors

Sep 24,2024

Resistors are fundamental components in circuits. After testing the conductivity of various materials and discovering the presence of current, early scientists gradually developed the concept of resistance. Scientists have discovered that copper, gold, and aluminum are excellent conductors with low resistance, while air, mica, and ceramics are considered resistors because they can greatly restrict the flow of current. Although industry insiders have long known about its resistance performance, the reliable resistors we know today have never been born until Otis Boykin created the first inexpensive and reliable resistor in 1961, allowing scientists to accurately control the amount of current transmitted to a certain component. With his breakthrough, the resistance of resistors to extreme temperatures and oscillations was greatly reduced, ultimately making low-cost production possible. With the US military, IBM, and numerous consumer electronics manufacturers placing orders to purchase Boykin's new resistors, their presence is ubiquitous from household appliances and computers to guided missiles.
