As an emerging technology, Quantum-dot Cellular Automata (QCA) has been extensively analyzed in the technical literature for implementing logic circuits; in this technology, the basic combinational circuit is the majority voter with three inputs. In this paper, the design of a logic gate which implements any combinational function of at most three input variables is presented. This type of gate...

quantum-dot cellular automata (qca) has low power consumption and high density and regularity. qca widely supports the new devices designed for nanotechnology. application of qca technology as an alternative method for cmos technology on nano-scale shows a promising future. this paper presents successful designing, layout and analysis of multiplexer with a new structure in qca technique. in thi...

complementary metal-oxide semiconductor (cmos) technology has been the industry standard to implement very large scale integrated (vlsi) devices for the last two decades. due to the consequences of miniaturization of such devices (i.e. increasing switching speeds, increasing complexity and decreasing power consumption), it is essential to replace them with a new technology. quantum-dot cellular...

For digital system designs, triple modular redundancy (TMR), which is a 3-tuple version of N-modular redundancy is widely preferred for many mission-control and safety-critical applications. The TMR scheme involves two-times duplication of the simplex system hardware, with a majority voter ensuring correctness provided at least two out of three copies of the system remain operational. Thus the ...

In this study, we introduced a probabilistic voter, regarding symbol probabilities in decision process besides majority consensus. Conventional majority voter is independent of functionality of redundant modules. In our study, proposed probabilistic voter is designed corresponding to functionality of the redundant module. We tested probabilistic voter for 3 and 5 redundant modules with random t...

A voting scheme constitutes an essential component of many fault tolerant systems. Two types of voters are commonly used in applications of real-valued systems: the inexact majority and the amalgamating voters. The inexact majority voter effectively isolates erroneous modules and is capable of reporting benign outputs when a significant disagreement is detected. However, an application specific...
