| Abstract: | To reduce the electronic product design lifecycle and increase the success rate of product design, a method of matching termination to solve the issue of signal integrity is presented. Firstly, the issue of signal integrity is analyzed. Then, a mathematical model based on analysis is constructed. It is pointed out that the difficulty in scheme design is to identify and evaluate key parameters. An application case of simulation analysis and parameter optimization demonstrated the effectiveness of the method ... |
