Reversible logic circuits have emerged as a promising technology having its applications in low power CMOS, Quantum Computing, nanotechnology, and optical computing. Power is the major constraint for any circuit Each circuit demands not only low power, but fast speed. This paper is focused on the efficient design of the full Adder/Subtractor with the help of half adder subtractor with single co...
In this paper a low power and low area array multiplier with carry save adder is proposed. The proposed adder eliminates the final addition stage of the multiplier than the conventional parallel array multiplier. The conventional and proposed multiplier both are synthesized with 16-T full adder. Among Transmission Gate, Transmission Function Adder, 14-T, 16-T full adder shows energy efficiency....
In this paper propose a new high performance 1 bit full adder cell using XOR/XNOR gate design style as well as lower power consumption. Simulation results illustrate the superiority of the resulting proposed adder against conventional 1-bit full-adder in terms of power consumption improvement performance (98% of 10T, 47% of 14T & 16T), propagation delay and PDP. We have performed simulations us...
Under ideal conditions, Reversible logic gates produce zero power dissipation. So these can be used for low power VLSI design. This paper proposes a new reversible parallel adder/subtractor using 4*4 Reversible DKG gate that can work singly as a reversible full adder and a full subtractor. A serial adder/subtractor is also designed in this paper using Reversible Universal Shift registers and DK...
Keywords: Self-checking adder Carry-select adder Fault localization Self-repairing adder Multiple faults a b s t r a c t In this paper we propose an area-efficient self-repairing adder that can repair multiple faults and identify the particular faulty full adder. Fault detection and recovery has been carried out using self-checking full adders that can diagnose the fault based on internal funct...
Full adders are important components in applications such as digital signal processors (DSP) architectures and micro-processors. In this paper, we propose a technique to build a total of 3 low power 10 transistor full adder using x-nor gates. We have done around 10 simulation runs of each adder for different frequencies, load capacitance and input patterns. Almost all the new adders consume les...
In this paper, we designed and simulated a low power one bit, 8-bit and 32-bit full adder circuits namely Novel 10T, N14T, FA24T, CPL (complementary pass-transistor logic) and DPL (double pass-transistor logic). All the adders are tested by using one bit, 8-bit and 32-bit ripple carry adder architecture using Tanner EDA tool version 13. 0. The one bit Novel 10T, N14T, XOR/XNOR function techniqu...
Full adder circuit is a basic building block for designing any arithmetic circuits. Due to high demands and need for low and high speed digital circuits with small silicon area scaling trends have increased tremendously. In this paper a new high speed full adder circuit is proposed with very less static and dynamic power dissipation which occupies less silicon area when compared with existing t...
In this paper we analyse a serial (ripple carry) and a parallel (Kogge-Stone) adder when operating in subthreshold at 100nm and 70nm. These are targeted for ultra low power consumption applications. The elementary gates used are threshold logic gates (perceptrons). Simulations have been performed both with and without considering the delay on the wires. These simulations confirm that wires play...
