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 fast low-power 1-bit full adder circuit suitable for nano-scale CMOS implementation is presented. Out of the three modules in a common full-adder circuit, we have replaced one with a new design, and optimized another one, all with the goal to reduce the static power consumption. The design has been simulated and evaluated using the 65 nm PTM models.

The increasing demand for low power VLSI can be fulfilled to a great extent by making proper changes in the circuit level and architectural level design. Addition is a fundamental operation, as it is used to implement more complex functions such as subtraction, multiplication, division etc. The Manchester Carry Chain adder design is preferred to other adders, regardless the number of bits becau...

-In recent years, low power circuit design has been an important issue in System on Chip (SoC) and VLSI design areas. Adiabatic logics, which dissipate less power than static CMOS logic, have been introduced as a promising new approach in low power circuit design. Adiabatic circuits are those circuits which work on the principle of adiabatic charging and discharging and which recycle the energy...

The binary adder is the critical element in most digital circuit designs including digital signal processors (DSP) and microprocessor data path units. As such, extensive research continues to be focused on improving the power delay performance of the adder. This paper proposes a new method for implementing a low power full adder by means of a set of Gate Diffusion Input (GDI) cell based multipl...

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...

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...
