طراحی یک مدار xor-xnor کم مصرف مقاوم در برابر نویز

با توجه به نقش اصلی گیت­های xnor-xor و با توجه به این که مدارهای بلوک­های ساختاری، پایه مدارهای محاسباتی بسیاری، از جمله ضرب­کننده­ها، تمام جمع­کننده­ها، مقایسه­گرها و دیگر مدارها هستند، روش­های جدید برای این مدارها به منظور بهبود دادن سرعت و توان پیشنهاد شده است. با کاهش مقیاس به فناوری زیرمیکرون (deep submicron) امنیت نویز یک پارامتر هم اهمیت با توان، سرعت و فضا شده است. در این مقاله عملکرد م...

Microelectromechanical XNOR and XOR logic devices

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.

Array Multiplier Using Xnor- Xor Cell

The multipliers are the key structure for designing high performance digital systems. Design considerations of multiplier include high speed, less power consumption, less PDP (power-delay product) and regularity of layout. These design parameters make it suitable for various compact low power VLSI implementations. This paper presents an application of the proposed XNOR-XOR cell for a 2x2 array ...

Realization of Xor and Xnor Gates Using Qca Basic Gates

Quantum dot cellular automata is an emerging nanoelectronic computational architecture which has the potential of faster speed, smaller size and minimum power consumption compared to transistor-based technology. In QCA, binary information are encoded as electronic charge configuration of a cell. Fundamental unit in building of QCA circuit is a QCA cell. A QCA cell is an elementary building bloc...

Low Power and High Performance Dynamic CMOS XOR/XNOR Gate

A hybrid network is proposed in dynamic CMOS XOR/XNOR gate to avoid signal skew and reduce the power consumption. Compared to the standard N type dynamic gate leakage power, dynamic power and layout area of the novel XOR/XNOR gate are reduced. In this paper we studied different technologies, their merits and demerits. Comparison of different technologies is completely on the basis of leakage po...
