Problems solved by technology

[0002] With the rapid improvement of the technology of today's electronic products, the operating frequency of electronic signals and the transmission speed of data are also continuously increasing. For circuit designers, differential transmission lines are very common design methods, but in actual circuit design In most cases, due to various constraints such as the size of the printed circuit board, the placement of components, and the layout and routing of the circuit design, the wiring must be turned, resulting in unnecessary common-mode noise, and then Affects signal integrity
[0003] In related technologies, the method of reducing common mode noise is: digging holes on the reference ground plane and adding compensation capacitors to the differential transmission lines, but digging holes on the ground plane will waste a lot of routing area and cause power integrity problems. The compensation capacitor will cause the reflection of the differential mode signal to increase

Abstract

The present application discloses a printed circuit board. The printed circuit board includes a differential transmission line for transmitting differential signals; an L-shaped wiring arranged inside the bend of the differential transmission line is used for connecting with the differential transmission line. A capacitor is formed; wherein, the L-shaped trace is grounded. The present application can reduce the common mode noise of the printed circuit board without drilling holes in the ground plane and adding compensation capacitors. The application also discloses an electronic device, a method for generating a printed circuit board model, and a computer-readable storage medium, which have the above beneficial effects.
