— In this paper, we report Magnetic Quantum Cellular Automata (MQCA) realization using multi-layer cells with tilted polarizer reference layer with a particular focus on the critical need to shift towards the multi-layer cells as elemental entities from the conventional single-domain nanomagnets. We have reported a novel spin-transfer torque current induced(More)
We propose a new switching probability model for combinational circuits using a<b>Logic-Induced-Directed-Acyclic-Graph</b>(LIDAG) and prove that such a graph corresponds to a<b>Bayesian Network</b>guaranteed to map all the dependencies inherent in the circuit. This switching activity can be estimated by capturing complex dependencies (spatio-temporal and(More)
In this paper, different circuits of Quantum-dot Cellular Automata (QCA) are proposed for the so-called coplanar crossing. Coplanar crossing is one of the most interesting features of QCA because it allows for mono-layered interconnected circuits, whereas CMOS technology needs different levels of metalization. However, the characteristics of the coplanar(More)
With the goal of building an hierarchical design methodology for quantum-dot cellular automata (QCA) circuits, we put forward a novel, theoretically sound, method for abstracting the behavior of circuit components in QCA circuit, such as majority logic, lines, wire-taps, cross-overs, inverters, and corners, using macromodels. Recognizing that the basic(More)
DEDICATION To my loving Father and Mother ACKNOWLEDGEMENTS I would like to take this golden opportunity to thank my major professor Dr. Sanjukta Bhanja. Without her this work wouldnt have been possible. She supported me and helped me to the core. She gave me complete freedom in research prospective. She has helped me a lot to mould myself as a researcher.(More)
In this paper, different circuit arrangements of Quantum-dot Cellular Automata (QCA) are proposed for the so-called coplanar crossing. These arrangements exploit the majority voting properties of QCA to allow a robust crossing of wires on the Cartesian plane. This is accomplished using enlarged lines and voting. Using a Bayesian Network (BN) based(More)
— In this work, we investigate the estimation of switching activity in VLSI circuits using a graphical probabilistic model based on Cascaded Bayesian Networks (CBN's). First, we develop a theoretical analysis for Bayesian inferenc-ing of switching activity and then derive upper bounds for certain circuit parameters which, in turn, are useful in establishing(More)
