It is generally considered that if the frequency of the digital logic circuit reaches or exceeds 45MHZ~50MHZ, and the circuit working above this frequency has accounted for a certain amount of the entire electronic system (for example, 1/3), it is called a high-speed circuit.
High Frequency PCB processing attention points.
The development history of electronic components is actually a condensed history of electronic development. Electronic technology is a new technology developed at the end of the 19th century and the beginning of the 20th century. It has developed most rapidly and been widely used in the 20th century. It has become an important symbol of the development of modern science and technology.
If the substance is distinguished by conductivity, it can be roughly classified into two types
IC refers to integrated circuits, which are made on semiconductors because semiconductors are the most suitable materials for realizing transistors, and transistors are the core devices of most circuits now. However, I want to write more here, tracing back to the origin, starting from the beginning of "circuit"
Chip, also known as microcircuit, microchip, integrated circuit (IC). It refers to the silicon chip containing integrated circuits, which is very small and often part of computers or other electronic equipment.
