Modeling MANETs using queuing networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Mobile Ad Hoc Networks (MANETs) are becoming an attractive solution to the services that require flexible establishment, dynamic and low cost wireless connectivity. Since nodes are mobile, routing results vary significantly ...
Design of low-voltage, low-power, wide-band CMOS LC VCO using active inductors
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
In this thesis the design of low-voltage, low-power, wide-band CMOS LC VCO using active inductor has been proposed. The oscillator is based upon the classic LC-tuned negative-resistance topology, with a novel active inductor ...
Asynchronous analog to digital converter
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Nowadays, asynchronous systems are becoming more popular for low power applications. Asynchronous Systems help to reduce metastability errors and clock skew errors. This thesis is about an asynchronous analog to digital ...
Design issues in direct conversion receiver
(Dhirubhai Ambani Institute of Information and Communication Technology, 2009)
The wireless system is being rapidly proliferated in our life. The growing of capacity in wireless communication requires a new type of wireless communication method which does not affect current work on circuits and systems ...
Design of multi-standard RF front end receiver using novel low IF topology
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
This thesis presents the multi-standard receiver architecture and the corresponding RF front-end design supporting Bluetooth and IEEE 802.11a WLAN standards. To maximize the level of component share in the proposed ...
Dual-band and shorted microstrip patch antenna design for communication system applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
Dual-band and miniaturized microstrip patch antennas are in much demand due to their small size, light weight and planar configuration. In this thesis, an attempt is made to design and analyze miniaturized microstrip patch ...
Design methodology for architecting application specific instruction set processor
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
Application Specific Instruction-set Processors (ASIP), also referred as extensible processors, represent the state-of-the-art microprocessor architecture. ASIPs are practically leading towards the realization of ...
Broadband microstrip antennas with switchable polarizations
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Microstrip antenna consists of a patch of metallization on grounded substrate. These are low profile, lightweight antennas, most suitable for aerospace and mobile application. They are replacing many conventional antennas ...
Analysis of charge injection in a MOS analog switch with impedance on source side
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Turning off of a transistor introduces error voltage at the output of Sample and Hold circuits
which are the key components of Analog to Digital Converters (ADCs) and hence limits their
accuracy of performance in high ...
Area reduction in 8 bit binary DAC using current multiplication
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
A proposed current multiplication technique is applied on 8 bit binary current steering Digital-to -Analog Converters with LSB 150 μA, to reduce area. MSB 1 and MSB 2 current are first kept half to reduce area and then ...
