Carrier recovery in software defined radio (SDR)
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
The work presented here, deals with the carrier synchronization in digital communication
system. The transmitter and receiver are two separate circuits located at a distance end and
rarely share same carrier frequency ...
Collusion resistant fingerprinting
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
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 ...
Community based co-operation protocol for social networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
In wireless ad-hoc networks, information propagates through several intermediate relay nodes. The mobiles in ad-hoc network have limited energy, so the nodes feel uncomfortable to act as a relay for other’s data transformation. ...
CMOS current-based mixed-signal architecture for vector-matrix multiplication
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
In present days electronic devices become faster. Computations like vector matrix
multiplication become more and more compliant and lengthy. For that CMOS based vectormatrix
multiplication architecture, with external ...
Design & layout of a low voltage folding & interpolation ADC for high speed applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2012)
Analog to Digital Converters (ADC) and Digital to Analog Converters (DAC) plays a vital role
in mixed analog signalling, communication and digital signal processing world. Now a day,
the demand for designing of high ...
D-latch based low power memory design
(Dhirubhai Ambani Institute of Information and Communication Technology, 2015)
Low power consumption is the main attraction of the digital circuit design in the
Sub threshold region of operation. In this region of operation less energy is
consumed for active operation and less leakage power is ...
CTS and CCOpt metodology's to achieve low skew-low power clock.
(Dhirubhai Ambani Institute of Information and Communication Technology, 2013)
In synchronous VLSI chips, clock distribution network plays an important role. The quality of clock network mainly effects the performance of the chip, because the speed of data transfer depends on clock signal. Achieving ...
Counting spanning binary trees of labelled undirected graphs
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
The number of spanning binary trees of a connected labelled undirectedgraph is an important quantity which is closely related to the reliability of thegraph as a network. Many problems and their applications in mathematics ...
Design and layout of single bit per stage pipelined ADC
(Dhirubhai Ambani Institute of Information and Communication Technology, 2011)
The concept of pipe-lining, often used in digital circuits, can also be applied in the analog domain. It helps to achieve higher speed where several operations must be performed serially. In this work, pipe-lining is ...
Design and implementation of high power amplifier using gallium nitride
(Dhirubhai Ambani Institute of Information and Communication Technology, 2016)
In recent years, the use of Gallium Nitride (GaN) transistors as active device inpower amplifier circuits has increased. The advancement in the technology forsuitable substrate has allowed the use of this very promising ...
