Recently, the influence of the silicon area on the delay time, power dissipation and the leakage current is a crucial issue when designing a full adder circuit. In this paper, an efficient full adder design referred to as 10-T is proposed. The new design utilized the use of XNOR gates instead of XOR in the full adder implementation and, as a result, the delay time and power dissipation are sign...

Reversible quantum computer is gaining interest for the future computer system. With the advent of quantum computer and reversible logic, design and implementation of all devices has received more attention. BCD digit adder is the basic unit of the more precise decimal computer arithmetic. The research objective is to increase speed of operation for addition of BCD numbers while minimizing the ...

As the requirement of low power high performance arithmetic circuits, in this paper we introduced a design of new MT-CMOS domino logic and FTL dynamic logic technique to design adder circuit. The MT-MOS transistors reduce the power dissipation by minimizing sub threshold leakage current in domino logic circuits introduced. The MT-NMOS transistor connected in discharging path of output inverter ...

Dynamic logic families offer good performance over traditional CMOS logic. This is due to the comparatively high noise margins coupled with the ease of implementation. The main drawbacks of dynamic logic circuits are lack of design automation, charge sharing, feedthrough, charge leakage, singleevent upsets, etc. But these draw backs can be eliminated using domino and NORA circuits but still lac...

In order to reduce the silicon area of the chip and optimize the power of arithmetic circuits, this paper proposes a low power carry look-ahead BCD (Binary Coded Decimal) adder which uses a four bit MOCLA (Multiplexer and Or gate based Carry Look Ahead Adder) that forms the basic building block. This proposed MOCLA style uses a 2 input MUX, OR gate and GDI (Gate Diffusion Input) based full adde...

In balancing the trade-off between power, area and performance, numerous efforts have been done. However, not much study has been done at the two extreme ends of the design spectrum, namely the ultra low-power with acceptable performance at one end (the main concern of this paper), and high performance with power within limit at the other. This paper is based on the exclusive use of subthreshol...

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...

This paper discusses a rail to rail swing, mixed logic style 1-bit 28-transistor (28T) full-adder, based on a novel architecture. The performance metrics: power, delay, and power delay product (PDP) of the proposed 1-bit adder is compared with other two high performance 1-bit adder architectures reported, till date. The proposed 1-bit adder has a 50% improvement in delay, and 49% improvement in...
