Course on Beyond CMOS Computing
06 Jun 2013 | Teaching Materials | Contributor(s): Dmitri Nikonov
Complementary metal-oxide-semiconductor (CMOS) field effect transistors (FET) underpinned the development of electronics and information technology for the last 30 years. In an amazing saga of development, the semiconductor industry (with a leading role of Intel) has shrunk the size of these transistors from 1000nm to 22nm. As this size approaches atomic limits, the research community is under pressure to find devices which complement CMOS and enable further improvement of performance of …
Uniform Methodology of Benchmarking Beyond-CMOS Devices
31 Oct 2012 | Online Presentations | Contributor(s): Dmitri Nikonov
Multiple logic devices are presently under study within the Nanoelectronic Research Initiative (NRI) to carry the development of integrated circuits beyond the CMOS roadmap. Structure and operational principles of these devices are described. Theories used for benchmarking these devices are overviewed, and a general methodology is described for consistent estimates of the circuit area, switching time and energy. The results of the comparison of the NRI logic devices using these benchmarks are presented. The promising devices - tunneling FET and spin wave devices - were predicted to perform > 1015 Integer Ops/s/cm2 with power < 1W/cm2.
Performance of Magnetic Quantum Cellular Automata and Limitations due to Thermal Noise
02 Jun 2011 | Papers | Contributor(s): Ajey Jacob, Dmitri Nikonov
Operation parameters of magnetic quantum cellular automata are evaluated for the purposes of
reliable logic operation. The dynamics if nanomagnets is simulated via Landau-Lifshitz-Gilbert equations with stochastic magnetic field corresponding to thermal fluctuations. It is found that in the macrospin approximation the switching speed does not change under scaling of both size and distances between nanomagnets. Thermal fluctuations put a limitation on the size of nanomagnets, since the gate …
