Description
Summary:Based on the equivalent circuit model, this research suggests an efficient technique to increase 3dB bandwidth of Copper-Carbon Nanotube composite interconnects. This technology is widely used inductance peak technology. Additionally, the electrical equivalent circuit model's the transfer function is generated using the ABCD parameter matrix approach. The relationship between the 3dB bandwidth of the interconnect at the global level for the 14nm technology node and the peaking inductance has been determined, taking into account the impacts of length, diameter and load resistance. The simulation results show that the bandwidth may be properly increased by increasing a peak inductance at the load side, but it can not be increased indefinitely. When the inductance is increased beyond a certain value, the bandwidth will remain stable. Also, the overshoot phenomenon will appear for larger inductance.
