High-Frequency Modeling of On-Chip Coupled Carbon Nanotube Interconnects for Millimeter-Wave Applications

This paper presents a high-frequency equivalent circuit model for on-chip coupled carbon nanotube (CNT) interconnects up to 100 GHz. By simplifying the circuit model, the S-parameters of on-chip coupled interconnects can be acquired and validated by comparing with the full-wave electromagnetic simulations. By virtue of effective complex conductivity, the high-frequency behaviors of coupled CNT interconnects are captured and studied, with the impacts of kinetic inductance treated appropriately.
