An area-efficient static CMOS carry-select adder based on a compact carry look-ahead unit
This paper presents a highly area-efficient CMOS carry-select adder (CSA) with a regular and iterative-shared transistor structure very suitable for implementation in VLSI. This adder is based on both a static and compact multi-output carry look-ahead (CLA) circuit and a very simple select circuit. Comparisons with other representative 32-bit CSAs show that the proposed adder reduces the area b...
متن کامل5TClocked Carry Look Ahead Adder Design Using MIFG
Abstract-Low-voltage and low-power circuit structures are substantive for almost all mobile electronic gadgets which generally have mixed mode circuit structures embedded with analog sub-sections. Using the reconfigurable logic of multiinput floating gate MOSFETs, 4-bit full adder has been designed for 1.8V operation. Multi-input floating gate (MIFG) transistors have been anticipating in realiz...
متن کاملImplementation of an Arithmetic Logic Using Area Efficient Carry Look- Ahead Adder
An arithmetic logic unit acts as the basic building blocks or cell of a central processing unit of a computer. And it is a digital circuit comprised of the basic electronics components, which is used to perform various function of arithmetic and logic and integral operations further the purpose of this work is to propose the design of an 8-bit ALU which supports 4-bit multiplication. Thus, the ...
متن کاملDesign of Area and Power Efficient Modified Carry Select Adder
Adders are one of the widely used digital components in digital integrated circuit design. The Carry Select Adder (CSA) provides a good compromise between cost and performance in carry propagation adder design. However, conventional CSA is still area-consuming due to the dual ripple carry adder (RCA) structure. In this paper, modification is done at gate-level to reduce area and power consumpti...
متن کاملPerformance Analysis of 32-Bit Array Multiplier with a Carry Save Adder and with a Carry-Look-Ahead Adder
In this paper, design of two different array multipliers are presented, one by using carry-look-ahead (CLA) logic for addition of partial product terms and another by introducing Carry Save Adder (CSA) in partial product lines. The multipliers presented in this paper were all modeled using VHDL (Very High Speed Integration Hardware Description Language) for 32-bit unsigned data. The comparison ...
