An Architecture for Designing Noise-Tolerant QCA Nanocircuits

Lee S-C, Hook IV L.R., University of Oklahoma, US

Due to many random factors from thermal fluctuations to wave interference, computation perfection in nanoICs is hard to achieve. Defects and faults arise from noise susceptibility of nanoICs which leads to unreliable results. A probabilistic [...]

Self-Healing Wire-Streaming Processors on 2-D Semiconductor Nanowire Fabrics

Wang T., Bennaser M., Guo Y., Moritz C.A., University of Massachusetts Amherst, US

One of the most promising underlying nanodevice technologies today for nanoscale integrated circuits are semiconductor nanowires (NWs) and arrays of crossed NWs. Researchers have already built FETs and diodes out of NWs. There has also [...]

Fault Tolerant Quantum Computation with new Reversible Gate

Vasudevan D.P., Lala P.K., Parkerson J.P., University of Arkansas, Fayetteville, US

Current CMOS technology will be promising only for the next two decades or less until it reaches its physical limit. Once the atomic level of system design comes to the road of technology, Quantum mechanics [...]

Fault Detection and Diagnosis Techniques for Molecular Computing

Tahoori M.B., Mitra S., Northeastern University, US

Fault detection and diagnosis techniques that are essential for defect tolerance, fault tolerance and self-repair of molecular computing systems are discussed. These techniques enable robust molecular computing system design protected from manufacturing defects and run-time [...]

Electronic Nanotechnology Based on Non-Binary Principles

Mathew J., Dubrova E., Tenhunen H., Royal Institute of Technology, Stockholm, SE

This paper describes alternative to binary number representations and discuss possibilities for implementing multiple-valued functions using chemically assembled electronic nanotechnology. The implementation of a four-valued adder using molecular diodes is presented. The proposed structure is [...]
