| Outline of Final Research Achievements |
To provide the basic considerations for electromagnetic (EM) radiation from practical asymmetrical differential-paired lines structure used in high-speed board/LSI layout, this study attempts to clarify the characteristics and to identify dominant imbalance and EM radiation factor, by a physics-based model. The frequency response of EM radiation from asymmetrical differential-paired lines can be identified using the physics-based model.
Negative group delay characteristics can be used to improve signal-integrity performance. The embedded Folded-Stepped Impedance Resonator (F-SIR) structure with open-stub resonator, for negative group delay and slope characteristics at high-frequency as well as low-insertion loss, is proposed. The proposed TL is fabricated on PCB, and then the concept is validated by measurement and simulation. The proposed method should be one of the potential candidates of a basic method for suppressing mode-conversion due to phase-difference.
