Efficient and Robust Delay-Insensitive QCA (Quantum-Dot Cellular Automata) Design

2006 21st IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems, 2006
The concept of clocking for QCA, referred to as the four-phase clocking, is widely used. However, inherited characteristics of QCA, such as the way to hold state, the way to synchronize data flows, and the way to power QCA cells, make the design of QCA circuits quite different from VLSI and introduce a variety of new design challenges.

Comparative Analysis of Full Adder Custom Design Circuit using Two Regular Structures in Quantum-Dot Cellular Automata (QCA)

IEEE International Symposium on Multiple-Valued Logic, 2019
Regular structures in Quantum-dot Cellular Automata (QCA) allow for ease of design and uniform clocking structure. The paper presents a comparative analysis of QCA realization using regular structures: Shannon-Lattices and Programmable Logic Arrays (PLAs)

A novel universal (FNZ) gate in quantum dot cellular automata (QCA)

IMPACT-2013, 2013
As transistor geometries are reduced, quantum effects begin to dominate device performance. At some point, transistors cease to have the properties that make them useful computational components. New computing elements must be developed in order to keep pace with Moore's Law.

Systematic Review on Full-Subtractor Using Quantum-Dot Cellular Automata (QCA)

2020
In earlier days, we used a CMOS-based subtractors; these are having lower specifications in terms of power dissipation, switching speed, and area. In this era, we are having nanotechnology which is of range 10−9, to reduce the overall specifications of the circuit.

Fault modeling and mapping for quantum-dot cellular automata (QCA) designs

2013 2nd International Conference on Advances in Electrical Engineering (ICAEE), 2013
This paper addresses the issue of fault modeling and mapping between a design done at the CMOS gate-level and one done using QCA technology. Since QCA and CMOS gate-level defects differ completely, it is important to investigate the mapping between classical single stuck-at fault (SSF) modeling and QCA defect and failure modes.

TCAM/CAM-QCA: (Ternary) Content Addressable Memory using Quantum-dot Cellular Automata

Microelectronics Journal, 2015
Abstract This paper describes a Content Addressable Memory (CAM) architecture and its ternary variant called Ternary Content Addressable Memory (TCAM) using the Quantum-dot Cellular Automata (QCA). QCA is an alternative to the current integrated circuit (CMOS) paradigm based on the characteristics of confinement and mutual repulsion between electrons.
