Quantum-dot Cellular Automata (QCA) provide very high scale integration potential, switching frequency, and have extremely low power demands, which make the QCA technology quite attractive for design implementation of large-scale, high-performance nanoelectronic circuits. However, state-of-the-art circuit designs were not derived by following a set universal rules, as is case CMOS circuits, and...

In this article, we try to model the effect of changes in threshold voltage two positive inputs negative ones using nanotechnology based on Quantum Dot Cellular automata (QCA). order do so, voter a Majority cell has been modified resulting amplifying upper and lower cells. Besides Brain-inspired approach can be used design very fast function with QCA.

The electronic industry has grown vastly in recent years, and researchers are trying to minimize circuits delay, occupied area and power consumption as much as possible. In this regard, many technologies have been introduced. Quantum Cellular Automata (QCA) is one of the schemes to design nano-scale digital electronic circuits. This technology has high speed and low power consumption, and occup...

Information in a quantum cellular automata architecture is encoded in the polarization state of a cell, i.e. in the occupation numbers of the quantum dots of which the cell is made up. Non-invasive charge detectors of single electrons in a quantum dot are therefore needed, and recent experiments have shown that a quantum constriction electrostatically coupled to the quantum dot may be a viable ...

Quantum-dot Cellular Automata (QCA) is a prominent paradigm that is considered to continue its dominance in thecomputation at deep sub-micron regime in nanotechnology. The QCA realizations of five-input Majority Voter based multilevel parity generator circuits have been introduced in recent years. However, no attention has been paid towards the QCA instantiation of the generic (n-bit) even and ...
