application of quantum-dot is a promising technology for implementing digital systems at nano-scale.  quantum-dot cellular automata (qca) is a system with low power consumption and a potentially high density and regularity. also, qca supports the new devices with nanotechnology architecture. this technique works based on electron interactions inside quantum-dots leading to emergence of quantum ...

Transient algebra is a multi-valued algebra for hazard detection in gate circuits. Sequences of alternating 0’s and 1’s, called transients, represent signal values, and gates are modeled by extensions of boolean functions to transients. Formulas for computing the output transient of a gate from the input transients are known for NOT, AND, OR and XOR gates and their complements, but, in general,...

This paper presents a new technique to implement exclusive-OR (XOR) gate by using MOS current mode logic (MCML) low-power tri-state buffer concept. The design of the proposed MCML XOR gate is carried out through analytical modeling of its static parameters. The proposed MCML XOR gate is analyzed and the performance is compared with the traditional MCML XOR gate. The theoretical propositions are...

-The notion of Carry Value Transformation (CVT) is a model of Discrete Deterministic Dynamical System. In this paper, we have studied some interesting properties of CVT and proved that (1) the addition of any two non-negative integers is same as the sum of their CVT and XOR values. (2) While performing the repeated addition of CVT and XOR of two non-negative integers “a” and “b” (where a ≥ b), ...

We have developed a new microelectromechanical logic device using the MEMS (Micro Electro Mechanical Systems) technology. This device consists simply of a single cantilever and two driving electrodes with two contact pads for electrostatic operation. Both exclusive NOR (XNOR) and exclusive OR (XOR) logic devices have been realized using this simple construction.

We show that a set of gates that consists of all one-bit quantum gates (U(2)) and the two-bit exclusive-or gate (that maps Boolean values (x; y) to (x; xy)) is universal in the sense that all unitary operations on arbitrarily many bits n (U(2 n)) can be expressed as compositions of these gates. We investigate the number of the above gates required to implement other gates, such as generalized D...

Quantum-dot Cellular Automata (QCA) technology is attractive due to its low power consumption, fast speed and small dimension, therefore, it is a promising alternative to CMOS technology. In QCA, configuration of charges plays the role which is played by current in CMOS. This replacement provides the significant advantages. Additionally, exclusive-or (XOR) gate is a useful building block in man...

A full adder circuit has been designed by using proposed 2T Exclusive-OR circuit and a transmission gate is used extensively in very large-scale integration (VLSI) application. The power dissipation of the adder is in range of 421.7256uw to 581.542uw in 0.35 um technology with a voltage supply is in the range o...
