“…For example, the full adder may be constructed with three majority gates and two inverters (3 magnetoelectric cells and 2 modulators). In contrast, a Boolean-based implementation requires a larger circuit with seven or eight gate elements (about 25-30 MOSFETs) [79]. The main reason Majority logic has been out of stage for decades is because its CMOS realization is ineffi cient.…”

Background and Objectives:There is a big impetus for the development of novel computational devices able to overcome the limits of the traditional transistor-based circuits. The utilization of phase in addition to amplitude is one of the promising approaches towards more functional computing architectures. In this work, we present an overview on magnonic logic devices utilizing spin waves for information transfer and processing. Materials and Methods: Magnonic logic devices combine input/output elements for spin wave generation/detection and 217 Твердотельная электроника, микро-и наноэлектроника A. Khitun, A. Kozhanov. Magnonic Logic Devices an analog core. The core consists of magnetic waveguides serving as a spin wave buses. The data transmission and processing within the analog part is accomplished by the spin waves, where logic 0 and 1 are encoded into the phase of the propagating wave. The latter makes it possible to utilize spin wave interference for logic functionality. The proof-of-concept experiments were accomplished on micrometer scale ferromagnetic Ni 81 Fe 19 and ferrite Y 3 Fe 2 (FeO 4 ) 3 structures. Results: We present experimental data on spin wave propagation and interference in magnetic microstructures. We also present experimental data showing parallel read-out of magnetic bits using spin...

-The continuing scaling down of complementary metal oxide semiconductor (CMOS) has led researchers to build new devices with nano dimensions, whose behavior will be interpreted based on quantum mechanics. Singleelectron devices (SEDs) are promising candidates for future VLSI applications, due to their ultra small dimensions and lower power consumption. In most SED based digital logic designs, a single gate is introduced and its performance discussed. While in the SED based circuits the fan out of designed gate circuit should be considered and measured. In the other words, cascaded SED based designs must work properly so that the next stage(s) should be driven by the previous stage. In this paper, previously NOT gate based on single electron box (SEB) which is an important structure in SED technology, is reviewed in order to obtain correct operation in series connections. The correct operation of the NOT gate is investigated in a buffer circuit which uses two connected NOT gate in series. Then, for achieving better performance the designed buffer circuit is improved by the use of scaling process.

“…The basic building block of every QCA circuit is majority gate and every QCA circuit can be built using Majority and inverter gate [3].The majority logic can be implemented in a different manner from that of Boolean logic. The Boolean logic operators (like AND, OR and their complements) and other digital functions can be implemented using Majority logic [4]. The majority logic can be termed as more powerful for implementing digital functions because of very small number of logic gates [5,6].…”

Quantum Cellular Automata (QCA) is an emerging nanotechnology and one of the top six technologies of the future. CMOS technology has a lot of limitations while scaling into a nano-level. QCA technology is a perfect replacement of CMOS technology with no such limitations. In this paper we have proposed one 2:1 multiplexer circuit having lowest complexity and area compared to the existing QCA based approaches. The proposed design is verified using QCADesigner. General TermsQCA, QCA Designer, Multiplexer.
