Analysis and Comparison: Full Adder Block in Submicron Technology

Abstract

The reduction in the operating voltage play a majorrole in improving the performance of the integratedcircuits.Apart from that lesser power consumption, reducedarea and smaller size of transistors are also the vital factors inthe design criteria and fabrication of the systems. This articleapproaches towards the increasing performance of the systemsby comparing different types of adder circuits. In this article, anew circuit has been designed using the TG technology. Basedon different parameters like average power consumption anddelay, it has been observed that the Carry look-ahead adderand Carry bypass adder consumes more power. TheComparative analysis of TG based 8-bit different AdderDesigns using 180nm technology using TANNER tool has beenconsidered.
