High speed, low offset voltage cmos comparator
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
The Analog to digital converters are the key interface blocks between the continuous time domain and the discrete-time digital domain. The performance of high-speed data conversion and digital communication interfaces is ...
High speed sample and hold circuit design
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Sampling of the time-varying input signal is the first step in any type of Analog to Digital (A/D) conversion. For Low Power and high-speed A/D converter, a high-performance Sample and Hold (S/H) circuit is needed as its ...
High-performance low-voltage current mirror design
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Design of high precision analog circuits requires accounting for the mismatch between nominally identical transistors. In this work, errors affecting CMOS current mirrors due to mismatch between identical transistors are ...
Investigation on multi-band fractal antennas for satellite applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Remote sensing is a very important application of satellite communication. In remote sensing applications, multiple frequencies are utilized. Use of different antennas for different frequencies is a complex task and so use ...
Negotiation for resource allocation on infrastructure as a service cloud
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
The Cloud is a computing platform that provides dynamic resource pools, virtualization, and high availability. Cloud computing infrastructures can allow enterprises to achieve more efficient use of their IT hardware and ...
Object segmentation in still camera videos
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
The goal of object segmentation is to simplify and change the representation of an image into more meaningful so that it can easily analyse. Segmentation is the process of partitioning the digital image into multiple ...
Resource allocation on infrastructure as a service cloud using policies
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Conventionally, a cloud refers to an Infrastructure as a service cloud. Infrastructure as a service cloud providers manage a large set of computing resources. These resources can be provided to cloud users on demand in the ...
Robust surface coverage using deterministic grid based deployment in wireless sensor networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
The rapid progress in the field of wireless communication ans MEMS technology has made wireless sensor networks (WSN) possible. These networks may have low cost sensors deployed which are capable of sensing any activity ...
Robust and secure watermarking scheme based on singular values replacement
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Digital watermarking is used to carry information by embedding information into the cover data in a perceptually visible or non visible manner. In today's sea of digital information, there are many problems associated like ...
Micro-level drought preparedness with information management and rural knowledge centres: a framework to support rural farm families
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Drought and desertification are serious problems that significantly affect hundreds of millions of people and ecosystems. When drought occurs, the farm communities are usually the first to be affected because of their heavy ...
