Abstract

Technology is growing at a faster rate after the evolution of VLSI, which mainly focuses on three major criteria-speed, area and power. All these criteria determine the compactness of a product in order to produce an efficient output at a higher rate by consuming less power. To achieve the above-mentioned factors, an efficient 8-bit Universal Shift Register (USR) has been designed using modified Gate Diffusion Input (mGDI) technique. The results have been simulated using the TANNER EDA tool and found to contribute for low power and area.

Highlights

CMOS (Complementary Metal Oxide Semiconductor) transistor takes the advantages of low static power consumption and reduced noise immunity
The low power technology, modified Gate Diffusion Input technique which is used in this paper provides guarantee to achieve the goals of VLSI. 8-bit Universal Shift Register (USR) has been designed and simulated based on the mGDI technique using TANNER EDA v 16.01 tool
The bulks of NMOS and PMOS are constantly connected to VDD and GND respectively which results in high power consumption

Summary

Introduction

Portable electronic devices have changed the world due to its low power design. In addition to these advantages, it has the lesser complexity Compared to other shift registers, USR has been recognized as the most efficient shift register due to its multi-purpose operation. Considering the three major goals of VLSI, which is to provide a high speed, compact device with a less power consumption, an 8-bit USR has been designed which promises to give all these features. The low power technology, modified Gate Diffusion Input (mGDI) technique which is used in this paper provides guarantee to achieve the goals of VLSI.
