As the complexity of integrated circuits (ICs) increase (e.g., more sophisticated circuit designs and/or more circuit components integrated into the ICs), digital routing channels connecting various circuit components may occupy more chip area to prevent certain interferences (e.g., interference caused by a channel crosstalk or coupling between adjacent digital routing channels), resulting in certain problems, such as reduced efficiency of chip area usage and increased power consumption. To solve such problems, inverter staggering circuits and/or coaxial shielding of digital routing channels may be used in the ICs to mitigate the interferences. The inverter staggering circuits and/or coaxial shielding may improve the robustness of digital signals transmitted via the digital routing channels with reduced interferences, resulting in enhanced signal integrity, chip area utilization, power saving, and the like.
