We know that once the circuit design is complete, it is handed off to a “PCB designer” who then makes the board layout. Now, with products as complex as tablets, smartphones, and even video games, no one person has anything to do with the PCB. Products are designed by teams of experts, and without effective…
How to reduce the mutual interference between digital signals and analog signals? Before designing, you must understand the two basic principles of electromagnetic compatibility (EMC): The first principle is to minimize the area of the current loop; the second principle is that the system uses only one reference plane. On the contrary, if there are…
