1v rail to tail operational amplifier design for sample and hold circuits
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
At low voltage, the input common mode voltage of Operational amplifier is limited which restricts its use as a buffer. This works deals with designing a rail to rail amplifier. The Thesis presents a 1V rail to rail operational ...
Knowledge management techniques towards answering engine
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
The growth of Internet era has brought magnitude of information at the disposal of end user being mobilized with the speed of electron. But this bless of information comes with a curse of ‘information overload’. Answer ...
Multiple watermarking schemes for copyright protection
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
Recent advances in digital communication and storage technologies have brought major changes for consumers. High capacity hard disks and DVDs can store a huge amount of audiovisual data. In addition, faster Internet ...
Frequency compensation technique for low voltage three stage operational amplifier
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
This thesis presents a new frequency compensation technique for low supply voltage three-stage operational amplifier at higher loads. It is based on the miller splitting and pole-zero cancellation using feed-forward path. ...
Resource discovery in computational grids: quantitative comparison and analysis of MDS and DHT
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Grid Information Services provided by most of the grid middlewares aim at discovering resources in wake of large number of Grid nodes. Many Grid Information Services (GIS) have been deployed in different Grid middlewares. ...
Investigation of low power design of left-right leap frog array multiplier
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
This thesis addresses the Low Power design of 12 bit LRLFAM at the Layout, circuit and logic levels. A new Low power Booth-Recoder (BR), and Multiplexer based partial product generated are designed using pass-Transistor ...
Traitor tracing for xml documents
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
Electronic documents are more easily copied and redistributed than paper documents. This is a major impediment to electronic publishing. One needs to think of various copy protection schemes for the documents. There are ...
Performance analysis of JDO in J2EE architecture
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
Data persistence is one of the most important aspects of any enterprise wide application. An enterprise data persistence solution must provide speedy client transactions, ensure data integrity over time, and be able to ...
Energy efficient secret aggregation for wireless sensor networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Sensor networks involves large amount of nodes spread over a region. Data aggre¬gation is an important technique for reducing the amount of data to be transmitted in the networks. Data confidentiality is a crucial requirement ...
Low power and high speed sample and hold circuit
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
In this thesis work the design of a high speed and low power CMOS sample and hold circuit as a front-end block of pipelined analog-to-digital converter is described. The circuit consists of bottom-plate sampling with ...
