THEORY, DESIGN, AND SIMULATION OF LINA: A PATH FORWARD FOR QCA-TYPE NANOELECTRONICS
Abstract
dc:description.abstractThe past 50 years have seen exponential advances in digital integrated circuit technologies which has facilitated an explosion of uses and functionality. Although this rate (generally referred to as "Moore's Law") cannot be sustained indefinitely, significant advances will remain possible even after current technologies reach fundamental limits. However if these further advances are to be realized, nanoelectronics designs must be developed that provide significant improvements over, the currently-utilized, complementary metal-oxide semiconductor (CMOS) transistor based integrated circuits. One promising nanoelectronics paradigm to fulfill this function is Quantum-dot Cellular Automata (QCA). QCA provides the possibility of THz switching, molecular scaling, and provides particular applicability for advanced logical constructs such as reversible logic and systolic arrays within the paradigm. These attributes make QCA an exciting prospect; however, current fabrication technology does not exist which allows for the fabrication of reliable electronic QCA circuits which operate at room-temperature. Furthermore, a plausible path to fabrication of circuitry on the very large scale integration (VLSI) level with QCA does not currently exist. This has caused doubts to the viability of the paradigm and questions to its future as a suitable nanoelectronic replacement to CMOS. In order to resolve these issues, research was conducted into a new design which could utilize key attributes of QCA while also providing a means for near-term fabrication of reliable room-temperature circuits and a path forward for VLSI circuits.
