Design of low power and high speed decoder for 1MB memory
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Technology scaling is accompanied by rise in leakage power dissipation. This thesis proposes a voltage controllable circuit in the feedback path of the decoder, which drastically reduces the standby leakage current with ...
Study of algebraic and state based testing techniques
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Sequential programs can be modeled as algebra or transitions on a state space. Whether a program is implemented according to its model is the question addressed by program testing. The thesis illustrates issues in constructing ...

(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
Direct Conversion RF transceiver is the enabling technique for the next generation cellular and personal communication devices striving for miniaturization, long life of battery and cost effectiveness. Existing techniques ...
Cache performance evaluation in DSR protocol through cross-layering for mobile ad hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Wireless mobile ad-hoc networks are being actively studied by many researchers these days. These networks are suitable to be used in various situations because of (i) their infrastructure-less property and (ii) the mobility ...
Design of the analog front end circuit for X-ray detectors
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
The Thesis presents a novel idea to efficiently read out the value corresponding to incident X-Ray, from X-Ray sensor. A system level solution has been proposed which is unique in itself in terms of approach. A simple ...
Mining effective association rules using support-conviction framework
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Discovering association rules is one of the most important tasks in data mining. Most of the research has been done on association rule mining by using the support-confidence framework. In this thesis, we point out some ...
Design of CMOS voltage controlled oscillator for high tuning range
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
The main objective of the work is to design a CMOS voltage controlled oscillator for higher tuning range. Today there is a great need for multi-standard wireless receivers in the wireless communications. A receiver is to ...
Extremely low voltage operational amplifier design with rail-to-rail input common mode range
(Dhirubhai Ambani Institute of Information and Communication Technology, 2006)
Increasing trends towards battery operated systems demand circuits to be designed at low voltages. Low voltage operation severely limits the operational amplifier as a voltage buffer as the input common mode range available ...
Web content outlier detection using latent semantic indexing
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Outliers are data elements different from the other elements in the category from which they are mined. Finding outliers in web data is considered as web outlier mining. This thesis explores web content outlier mining which ...
Design of multi-band fractal antenna for satellite navigation application
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
Recent efforts by several researchers around the world to combine fractal geometry with electromagnetic theory have led to a plethora of new and innovative antenna designs. This research proposal has been primarily focused ...
