High-Crosstalk Robustness Transmission Line Interconnect in Si LSI using Zero-Crosstalk Structure

This paper proposes a novel bus line structure using differential transmission lines, which equips high-density and high crosstalk-robustness. The feasibility of this structure is discussed from results of two-dimensional electromagnetic simulation and time-domain measurement. Measurement results show that the bus line has higher crosstalk robustness than that of the conventional co-planar line. The bus line can reduce effective density of 55% as compared with the conventional coplanar line
