Design of CMOS front end for 900MHz RF receiver
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
Portable wireless personal communication systems such as cellular phones, message pagers, and wireless modems traditionally have been built from a mixture of IC technologies. In fact if we section a commercial cellular ...
Design of a CMOS variable gain amplifier
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
In advanced CMOS technologies as device dimensions are decreasing, requirement for lower supply voltages are increasing to make certain device reliability. So, challenges for analog circuit designers are to discover new ...
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, ...
Design of a high speed I/O buffer
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
In high speed serial transmission of data, output buffer creates the bottleneck. Current Mode Logic (CML) buffers have gained wide acceptance in most high speed serial interfaces as they reach speed of the order of Gbp/s. ...
Design of AHB-Wishbone bridge
(Dhirubhai Ambani Institute of Information and Communication Technology, 2004)
System-on-Chip (SoC) design is performed through integration of pre-designed components, called intellectual Property (IP). Design reuse is a critical feature in SoC design. Design reuse is the simple concept of using IP ...
Design of low voltage high performance, wide bandwidth current feedback amplifier with complementary input pair
(Dhirubhai Ambani Institute of Information and Communication Technology, 2007)
This thesis presents the work done on the design of a low voltage high performance, wide bandwidth current feedback amplifier [CFA] with complementary input pair. The design is carried out in 1.8 V, 0.18 micron CMOS process. ...
Design of voltage reference circuits
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Shrinking device dimensions in advancing CMOS technologies require lower supply voltages to ensure device reliability. As a result, analog circuit designers are faced with many challenges in finding new ways to build analog ...
Differential geometry and image processing
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
There are various ways of observing and interpreting images. At higher levels of abstraction, one looks at an image as collections of objects, while at the other end it is just a collection of curves and surfaces. We study ...
Effect of channel asymmetry on reputation based cooperation mechanisms in mobile ad-hoc networks
(Dhirubhai Ambani Institute of Information and Communication Technology, 2008)
Enforced cooperation among MANET nodes is an active research issue. In applications, where the users have different goals and there is no central authority to control them, users may become selfish. These nodes may not ...
Distributed clustering for heterogeneous wireless sensor network in data gathering applications
(Dhirubhai Ambani Institute of Information and Communication Technology, 2005)
Wireless Sensor networks have revolutionized the paradigm of gathering and processing data in diverse environment such as, wildlife area, kindergarten or agriculture farm. The nodes in these networks usually have a very ...
