FULL ADDER CIRCUIT DESIGN WITH LOW POWER AND HIGH SPEED AT 0.25µM CMOS TECHNOLOGY USING TANNER EDA

Abstract

A CMOS Full Adder is designed using Tanner EDA Tool based on 0.25µm CMOS Technology. In the arithmetic logic unit (ALU), the full adder cell is one of the most frequently utilized digital circuit components and the fundamental functional unit of all computational circuits. Right now, a lot of work has been done to improve the architecture and functionality of full adder circuit designs. In this research, two innovative 1-bit full adder cell designs are developed using ten transistors and 0.25mm CMOS technology (10-T). Tanner software tools will be used in the design of the CMOS full adder to simulate the schematic and layout as well as compare the schematic and layout for the purpose of determining precise design limitations. As part of this, we are going to perform the simulation of the CMOS full adder using T-SPICE of Tanner EDA and its layout design using the Microwind tool. The parameters such as power consumption, Area, Propagation Delay, and Power Delay Product (PDP) are evaluated to analyze the proposed one-bit full adder
