A Loss Optimization Method Using WD Product for On-Chip Differential Transmission Line Design

This paper proposes a loss optimization method for a high-speed transmission line on Si LSI. One of the most important issues for a transmission line interconnection is loss reduction of signal lines. Characteristics of differential transmission lines are evaluated by on-wafer measurement. It is shown that attenuation characteristics depend on the product of a line width and a line-to-line distance. The simple attenuation model is proposed
