The main constraints in recent trends of VLSI technology are power, area and delay. CMOS designs occupy more area and dissipate more power. Power dissipation results in heating up of an IC which directly affects the reliability and performance. Multipliers are the integral part of major application systems like Microprocessor, Digital Signal Processor (DSP) etc., so it is necessary to optimize the...
Built-in Self Test (BIST) is more appropriate for testing any VLSI circuits as it provides a larger range for low power applications. Test pattern generator is the vital module in BIST. Linear Feedback Shift Registers (LFSR) is broadly used in BIST for generating test vectors as it produces highly random test pattern. This paper mainly aims at design and implementation of power efficient LFSR using...
Conventional Complementary metal oxide semiconductor circuits (CMOS) dissipate energy in the form of bits of information. This dissipation of energy is in the form of power dissipation and plays a very important role as far as low power design is considered. Today, most digital circuits are being designed using Reversible Logic. Design based on Reversible Logic helps in reducing heat dissipation,...
The growing interest for flexible electronic applications has made Thin film Transistors (TFT) a hot topic of research today. Many different types of TFT devices are reported for a variety of applications. In this paper we have studied the behavior of drain current of amorphous silicon TFT with respect to different parameters. During the study the parameter of interest is varied while the other parameters...
The conventional way of killing weeds in a crop plantation is to spray herbicides throughout the plantation. This results in contamination of the food crops and also the yield becomes less as some of the crop plants die along with the weeds. Thus there is a need for a smart weed control system. In this paper, an image processing algorithm is used to take images of the plantation rows at regular intervals...
Automobiles and computing technologies are creating a new level of data services in vehicles. The Automobile Black Box has functions similar to an airplane black box. It is used to analyze the cause of vehicular accidents and prevent the loss of life and property arising from vehicle accidents. This paper proposes a prototype of an Automobile Black Box System that can be installed into vehicles. The...
Memories are integral parts of most of the digital devices and hence reducing power consumption of memory is very important in improving the system performance, efficiency and stability. Most of the embedded and portable devices use SRAM cells because of their ease of use as well as low standby leakage. Standard CMOS 6T SRAM cell uses two bit-lines and a word line for both read and write operations...
Over the past few years, the Integrated circuits design and verification has become increasingly complex. Industry, to overcome this problem has shifted to Electronic System Level (ESL) design flow. The ESL design at higher level of abstraction is called Virtual System Prototype (VSP). Each Intellectual Property (IP) in VSP should be verified Block level (Standalone verification) and in system level...
The Short Message Service (SMS) is one of the most successful services in existing cellular networks. The SMS provides a means of sending messages of limited size to and from Global System for Mobile Communications (GSM) or Universal Mobile Telecommunications System (UMTS) phones. SMS technology has evolved out of the GSM standard and presently, the 3rd Generation Partnership Project (3GPP) maintains...
