Realization of FPGA based digital controller
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Field Programmable Gate Array (FPGA) can be used to enhance the efficiency and the flexibility of digital controller. FPGA implementation of digital controllers leads to real time realizations with small size and high ...
Column decoder for memory redundant cell array
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
As the semiconductor technology advances, the yield of memory chip is reducing. The cause of yield degradation is errors in manufacturing process associated with tight geometries. The thesis work proposes a redundancy ...
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 ...
Design of row decoder for redundant memory cell (SRAM)
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
In the modern technology, the error occurring in memory circuits has increased and the yield of manufacturing has reduced. In order to solve these problems, this thesis proposed a redundancy circuit for faulty row in memory ...
Design of the high speed, high accuracy and low power current comparators
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
Comparators are non linear, decision making analog circuits, which find wide spread application in data converters, data transmission and others. Comparison can be done in terms of “Voltage” or “Current”.
A current ...
High speed, low offset voltage cmos comparator
(Dhirubhai Ambani Institute of Information and Communication Technology, 2010)
The Analog to digital converters are the key interface blocks between the continuous time domain and the discrete-time digital domain. The performance of high-speed data conversion and digital communication interfaces is ...
