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 ...
Radiation analysis of microstrip active (amplifier) and passive (antenna) structures
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Analysis of radiation from a microstrip amplifier and a newly proposed microstrip antenna is presented. Microstrip amplifier is analyzed replacing the MMIC structure by an equivalent S2P model and remaining portion being ...
Transaction based verification of discrete wavelet transform IP core using wishbone transactor
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Verification is major concern in product development life cycle. The number of human hours required writing a test bench and choice of verification approach is the major contributor in the Non Recurring Engineering (NRE) ...
