In this paper, we propose a novel multiplexer-based full adder design, denoted as MUXFA, by using regular modules for arithmetic applications. The MUXFA full adder is composed of three identical modules, in which each module separately operates for XOR-XNOR function, sum function, and carry function. The structure of the multiplexer-based full adder can be easily constructed by merely a single ...

This paper presents a novel low-power and high-speed 1-bit full-adder, which is designed based on pass transistor and TG logics. The main advantage of this design is low propagation delay and lowpower consumption, which leads to achieving lower PDP than others. Intensive HSPICE simulation shows that the new full-adder consumes around 28.5% less power than 14T adder; moreover its PDPis 30% less ...

Adiabatic logic is used to minimize the energy loss during operation of the circuit. Using two-phase adiabatic static CMOS logic (2PASCL) the power consumption can be reduced. This paper compares the power consumption of Static Energy Recovery Full Adder(SERF) and the proposed full adder using two phase adiabatic static CMOS logic(2PASCL). The average power consumption of proposed full adder is...

Full Adder is the basic building block for various arithmetic circuits such as compressors, multipliers, comparators and so on. 1-bit Full Adder cell is the important and basic block of an arithmetic unit of a system. Hence in order to improve the performance of the digital computer system one must improve the basic 1-bit full adder cell. In this, Full Adder is designed by using Hybrid-CMOS log...

This paper describes the speed of the design is limited by size of the transistors, parasitic capacitance and delay in the critical path. Power consumption and speed are two important but conflicting design aspects; hence a better metric to evaluate circuit performance is power delay product (PDP).The driving capability of a full adder is very important, because, full adders are mostly used in ...

This paper proposes two reversible logic gates, HNFG and HNG. The first gate HNFG can be used as two Feynman Gates. It is suitable for a single copy of two bits with no garbage outputs. It can be used as “Copying Circuit” to increase fan-out because fan-out is not allowed in reversible circuits. The second gate HNG can implement all Boolean functions. It also can be used to design optimized add...

In this paper, the various low power delay product full adder circuits have been analyzed. The adder is the fundamental blocks of any arithmetic circuit, so even a small reduction power or delay leads to improved performance of the circuit with optimal power saving. A 10T adder technique is the famous low power delay product full adder circuits with minimum transistor count. A new 10T technique...

A power-efficient 8-bits digital adder using the new arithmetic A2 redundant binary representation is presented. This structure is very suitable for implementation in VLSI of mixed-signal circuits built around Multiplier Digital to Analog Converter (MDAC) cells. Using a reduced transistor count Full-Adder cells shows that our approach significantly reduces the power consumption of such adders c...
