Abstract

Carbon Nanotube (CNT) has become the promising candidate for replacing the traditional Copper (Cu) based interconnect systems in future technology nodes. This paper presents an analytical model for timing and crosstalk in the CNT based nano-interconnect systems. The proposed model is compared with SPICE and it is found that the proposed model is 100% accurate with respect to SPICE and in an average ~250 times faster than SPICE. Using the proposed analytical model the crosstalk noise, delay, overshoot/undershoot are estimated in CNT based nano-interconnects for three different CNT parameters; CNT diameter, length, and metallic fraction.
