The Cascade Carry Array Multiplier -A Novel Structure of Digital Unsigned Multipliers for Low-Power Consumption and Ultra-Fast Applications

Annals of Emerging Technologies in Computing (AETiC), 2019

This article presents a low power consumption, high speed multiplier, based on a lowest transistor count novel structure when compared with other traditional multipliers. The proposed structure utilizes 4×4-bit adder units, since it is the base structure of digital multipliers. The main merits of this multiplier design are that: it has the least adder unit count; ultra-low power consumption and the fastest propagation delay in comparison with other gate implementations. The figures demonstrate that the proposed structure consumes 32% less power than using the bypassing Ripple Carry Array (RCA) implementation. Moreover, its propagation delay and adder units count are respectively about 31% and 8.5% lower than the implementation using the bypassing RCA multiplier. All of these simulations were carried out using the HSPICE circuit simulation software in 0.18 µm technology at 1.8 V supply voltage. The proposed design is thus highly suitable in low power drain and high-speed arithmetic electronic circuit applications.

Design & Implementation of 8x8 Multiplier Unit using MT-CMOS Technique

This paper deals with various multipliers implemented using CMOS logic style and their comparative analysis on the basis of power and PDP (Power delay product). A variety of multipliers have been reported in the literature but power dissipation and area used by these multiplier circuits are relatively large. This paper proposed a high performance and power efficient 8x8 multiplier design based on Vedic mathematics using CMOS logic style. Power consumption plays an imperative role specifically in the field of VLSI today, every designer be it an analog circuit or a digital circuit designer is concerned about the amount of power his or her circuit is going to consume in the end. The use of Vedas not only abates the carry propagation taking place from lsb to msb but also produces the partial product and there sums in the same step. Vedic mathematics based multipliers thus causes least delay and consume least power than any other type of multipliers in the literature. The proposed MTCMOS implementation of Vedic multiplier is up to 24.55% power efficient and about 98% speedy as compared to the conventional CMOS implementation of Vedic multiplier

Implementation of an 8-bit Low-power Multiplier based on Reversible Gate Technology

Reversible logic has attracted tremendous interest among the researchers in the low power VLSI field due to their simple structure and improved energy efficiency. In this paper, the implementation of an 8-bit low power multiplier based on reversible gate technology is reported. The structure of the reversible gate multiplier consists of the following components: the first part is the reversible partial product generator circuit (PPGC) which will be realized by a reversible AND gate; the second part is constructed of several TSG gates whose function is to add the carryout of the previous level and PPCG of current level together. In the second part, some XNOR gates and NOR gates with improved designs to save power and speed up the performance are presented. The 8-bit reversible gate multiplier is designed and simulated in PSPICE. PSPICE simulation verifies the correct function of the multiplier. In order for comparison, an 8-bit static CMOS multiplier is also designed. PSPICE power simulation is used to simulate the power consumption of both the reversible gate multiplier and the static CMOS multiplier for the same given input pattern sequence. Simulation results show that the reversible gate multiplier leads to effective power saving compared to the static CMOS multiplier.

Design of Multiplier using Low Power CMOS Technology

The paper presents a low Power consumption plays a vital role in the present day VLSI technology. Power consumption of an electronic device can be reduced by adopt changed design styles. Multipliers play a most important role in high concert systems. This project focus on a novel energy efficient technique called adiabatic logic which is based on energy renewal principle and power is compared by designing a multiplier. CMOS technology plays a main role in designing low power consuming devices, compared to different logic family CMOS has less power dissipation. Adiabatic logic method is assumed to be an attractive solution for low power electronic applications. By using Adiabatic techniques energy dissipation in PMOS network can be minimized and selection of energy stored at load capacitance can be recycled instead of dissipated as heat. Tanner EDA tools are used for simulation.
