In this work, we have proposed an abcd parameter matrix based model to analyze the impact of mutual inductance on the crosstalk induced effects (i.e. delay and noise) in two identically coupled SWCNT (i.e., Single walled carbon nanotube) bundle interconnects. For our study we have considered both in-phase and out of phase switching of those nano-interconnects of varying width, length and sparsity (i.e., sparse or dense bundle). Results are obtained by simulating our proposed model in MATLAB. It is observed that, from the performance point of view, sparse bundles are most effective as longer and wider global level interconnects. Whereas, dense bundles can only be used as shorter and thinner global level interconnects. From the peak noise voltage perspective, dense bundles are suitable as longer and wider global level interconnects. Sparse bundles are advantagious as shorter and thinner global level interconnects. It is also inferred that mutual inductance plays a key role for the switching of the interconnects in same phase and almost no role when interconnects switch in opposite phase. Both mutual inductance and coupling capacitance degrades the signal integrity and overall reliability of the interconnects in the nanometric regime.

Wide area measurement is significant for modernized control of power system. Phasor measurement unit (PMU) being the prime element for wide area measurement system (WAMS), it provides proper feedback to the closed looped controller to take proper steps during power system transients. This paper aims to measure the state of six bus power system in off-nominal frequency condition. To achieve this firstly a three phase PMU is simulated using recursive algorithm and then the algorithm is made frequency adaptive by re-sampling. Pseudo measurement using abcd parameter is also proposed and implemented.

Crosstalk induced overshoot/undershoot effects in Multilayer Graphene Nano Ribbon interconnects (MLGNRs) are investigated using abcd parameter matrix approach for intermediate level interconnects at 8 nm technology node. The worst case crosstalk induced peak overshoot voltage for perfectly specular doped multilayer zigzag GNR interconnects is comparable to that of copper interconnects. It is observed that the performance of neutral GNR interconnects is better than that of its doped counterpart in terms of peak crosstalk induced overshoot voltage. But from the perspective of effective electric field across the gate oxide, the multilayer doped GNR interconnects outperform neutral ones and copper interconnects for all the cases. Finally, our analysis has shown that from the gate oxide reliability perspective, the perfectly specular doped multilayer zigzag GNR interconnects are significantly advantageous to copper interconnects for future generation Integrated circuit technology.

Due to continued scaling of feature sizes, signal integrity and performance of today's copper based nanoscale interconnects are severely impacted. In this work, an abcd parameter based model is presented for fast and accurate estimation of crosstalk delay and noise for identically coupled copper based nano-interconnect systems. Using the proposed analytical model, the crosstalk delay and noise are estimated in copper based nano-interconnects for intermediate and global interconnects at the future Integrated circuit technology nodes of 21 nm and 15 nm respectively. The proposed model has been compared with SPICE and it is found that both the crosstalk delay and noise model are almost 100% accurate as SPICE and in an average similar to 22 times and similar to 40 times faster than SPICE respectively.

In the proposed work, crosstalk effects are investigated in two identically coupled SWCNT bundle interconnects at 21 nm and 15 nm technology nodes for intermediate and global interconnects. An abcd parameter based approach has been used to investigate crosstalk delay and noise in both sparse and dense SWCNT bundle interconnect system. The simulation results show that the proposed model is not only similar to 100% accurate but also almost 6 times faster than SPICE. The worst case crosstalk induced delay and peak crosstalk noise voltages for SWCNT bundle interconnects are compared to those of conventional copper (Cu) interconnects at the intermediate as well as global level interconnects. Simulation results also confirm that dense SWCNTs are always ahead of sparse SWCNTs with respect to performance advantage numbers over copper for every levels of interconnects and irrespective of technology nodes. As far as the worst case peak crosstalk noise is concerned, there is a critical length after which the performance of the dense SWCNT bundles is better than that of its sparse counterpart. Simulation results also prove that dense SWCNT bundled interconnect is a potential alternative to Copper interconnects in future nanoscale integrated circuits with respect to performance as well as signal integrity issues.
