摘要
A circuit structure for modifying characteristic impedance by using different reference planes is provided. The structure comprises an analog signal line, a digital signal line, a corresponding reference plane for analog signals and a corresponding reference plane for digital signals. Wherein, the line width of the analog signal line is the same as that of the digital signal line. In addition, the distance between the analog signal line and the corresponding analog signal reference plane is longer than the distance between the digital signal line and the corresponding digital signal reference plane. Accordingly, the characteristic impedance mismatch during signal transmission can be solved and the quality of signal transmission can be improved.
