Design of a low power high slew rate OPAMP and to study its impact on sigma delta modulator's performance
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
This thesis presents the work done on the design of a low-power, high slew rate opamp and subsequently the design of a fully-differential second order Switched-Capacitor architecture of a Sigma Delta modulator in 1.8 V, ...
Distributed caching mechanism for video on demand on the Internet
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Video on Demand applications in the Internet are delay sensitive and highly resource intensive applications. Such applications require streaming of large video files in a time bound manner. Because large volume in terms ...
Low power BIST architecture for fast multiplier embedded core
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
A typical core is deeply embedded in the chip of a system so that direct access to its input/output is not possible. Built in self test (BIST) structures are excellent solutions for testing embedded cores.
In this work, ...
Low power high speed amplifier design
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
The operational amplifier (op-amp) is one of the important component in analog to digital converters. The power consumption of these converters mostly depend on the op-amps used. The accuracy and speed performance of analog ...
Performance evaluation of differentiated services over MPLS
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
There is a compelling need to provide Quality of Service (QoS) within Internet with the introduction of multimedia applications, video conferencing etc. These applications demand high resource guarantees and timeliness of ...

(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
In the world of high-speed communications, systems involving high-speed data transfer require circuits with innovative features for good performance in terms of speed and power consumption. These data transfer systems ...
Study of face recognition systems
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Face Recognition comes under the general area of object recognition and has attracted researchers in the pattern recognition community for the past thirty years. The significance of this area has grown rapidly largely for ...
Efficient scan-based BIST scheme for low heat dissipation and reduced test application time
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Switching activity during test application can be significantly higher than that during normal circuit operation in many circuits. This is due to the fact that the correlation between consecutive test vectors is significantly ...
hybrid approach to digital image watermarking using informed coding, informed embedding and spread spectrum
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
The growth and popularity of the Internet has led to the data storage of multimedia data (audio, image and video) in digital form. The digitization form of multimedia data can be copied easily and then distributed again ...
Gaussian mixture models for spoken language identification
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Language Identification (LID) is the problem of identifying the language of any spoken utterance irrespective of the topic, speaker or the duration of the speech. Although A very huge amount of work has been done for ...
