Design of Testable Universal Logic Gate Targeting Minimum Wire-Crossings in QCA Logic Circuit

2010 13th Euromicro Conference on Digital System Design: Architectures, Methods and Tools, 2010
This work proposes a testable QCA (Quantum-Dot Cellular Automata) logic gate (UQCALG) realizing the universal functions. The design of UQCALG is based on the Coupled Majority Minority (CMVMIN) QCA structure with the target to reduce wire crossings as well as the number of clock cycles required to operate a QCA circuit.

Multifunction reversbile logic gate: Logic synthesis and design implementation in QCA

2017 International Conference on Computing, Communication and Automation (ICCCA), 2017
Quantum-dot Cellular Automata (QCA) is a newly developed paradigm for digital design. It explains how computation can be performed using nano sized quantum dots. One of the trending application of QCA is the design of reversible logic circuits and gates. Reversible logic is a dissipation less digital logic.

Implementation of Ex-OR gate using QCA with NNI logic

2017 International Conference on Wireless Communications, Signal Processing and Networking (WiSPNET), 2017
Quantum Dot Cellular Automata (QCA) is an intriguing transistor-less technology which can be rendered to switch from the existing CMOS technology. The basic logic state in QCA is determined by the polarity of electrons in a QCA cell rather than voltage level provided by the source. Basically, QCA consists of a majority voter gate and an inverter.

Concurrently testable FPGA design for molecular QCA using conservative reversible logic gate

2009 IEEE International Symposium on Circuits and Systems, 2009
Reversible logic is attracting the researchers attention for fault susceptible nanotechnologies including molecular QCA. In this paper, we propose concurrently testable FPGA design for molecular QCA using conservative reversible Fredkin gate. Fredkin gate is conservative reversible in nature, in which there would be an equal number of 1s in the outputs
