A clear protocol for synthesis of sequential reversible circuits from any particular gate library has been provided. Using that protocol, reversible circuits for SR latch, D latch, JK latch and T latch are designed from NCT gate library. All the circuits have been optimized with the help of existing local optimization algorithms (e.g. template matching, moving rule and deletion rule). It has be...

The Fredkin gate (Fredkin & Toffoli, 1982) is a Boolean logic gate that consists of 3 inputs and 3 outputs. This gate is universal for computational logic, and more importantly, it is reversible in the sense that the mapping between its inputs and outputs is bijective. In this paper, we realize the logic function of a Fredkin gate based upon two simple reversible elements (Lee, et al. 2008) tha...

Reversible logic is becoming an important research area which aims mainly to reduce power dissipation during computing. In this paper we introduce a new parity preserving reversible gate PPPG (a 5x5 gate). This gate is universal in the sense it can synthesize any arbitrary Boolean function. It is also a parity preserving gate in which the parity of input matches the parity of the output. This p...

Reversible circuits have applications in digital signal processing, computer graphics, quantum computation and cryptography. In this paper, a generalized k*k reversible gate family is proposed and a 3*3 gate of the family is discussed. Inverter, AND, OR, NAND, NOR, and EXOR gates can be realized by this gate. Implementation of a full-adder circuit using two such 3*3 gates is given. This full-ad...

The study of organic field effect transistors has expanded from its original objectives in developing organic semiconductors in which charge carriers have high mobility to focusing increasingly on opportunities arising from the design of electronic interfaces. Interfaces can have an important functional role in devices, for example a reconfigurable interface which responds reversibly to externa...

Reversibility plays a fundamental role when the possibility to perform computations with minimal energy dissipation is considered. Many papers on reversible computation have appeared in literature: the most famous are certainly the work of Bennett on (universal) reversible Turing machines and the work of Fredkin and Toffoli on conservative logic. The latter is based upon the Fredkin gate, a rev...

Quantum-dot cellular automata, is an extremely small size and a powerless nanotechnology. It is the possible alternative to current CMOS technology. Reversible QCA logic is the most important issue at present time to reduce power losses. This paper presents a novel reversible logic gate called the F-Gate. It is simplest in design and a powerful technique to implement reversible logic. A systema...

Reversible, or information-lossless, circuits have applications in digital signal processing, communication, computer graphics and cryptography. They are also a fundamental requirement for quantum computation. We investigate the synthesis of reversible circuits that employ a minimum number of gates and contain no redundant input-output line-pairs (temporary storage channels). We propose new con...

In recent years low power and small size are the keyword in the IC industry. This is where the importance of reversible gate and QCA (Quantum dot cellular automata) comes in. In nonreversible gates there is a definite amount of power loss involved. Interest in reversible computation arises from the desire to reduce heat dissipation, thereby allowing – higher densities and higher speed. The QCA ...
