Power-Aware System-on-Chip Test Optimization through Frequency and Voltage Scaling
(2014-04-29)
A System-on-Chip (SoC) is a complete system that has been integrated onto a single chip. An SoC is often designed by embedding reusable blocks called cores. With shrinking device sizes, SoC cores are growing in number and ...
Reliability, Scalability and Security in Smart Utility Networks
(2014-05-01)
With the rapid increase in deployment of smart meters across North America, resource
consumption data of utilities such as water, gas and electricity is being collected at a much higher
granular level. The huge amount ...
Dual-Threshold Voltage Design of Sub-Threshold Circuits
(2014-06-18)
Threshold voltage of MOSFET technology represents the value of the gate-source voltage
when the current in a MOS transistor starts to increase significantly since the conduction
layer just begins to appear. However, a ...
Simulation and Analysis of a Metamaterial Filter on a Flexible Liquid Crystal Polymer Substrate
(2014-04-25)
Since 1968 there has been an ever increasing interest in the study of metamaterials. These man-made substances have tremendous potential to change the scientific study of optics, communications, and the overall RF regime. ...
Univariate and Dynamic Multivariate Analysis of Functional MRI Data
(2014-04-23)
Functional magnetic resonance imaging (fMRI) has been increasingly used in the past decade for inferring brain function in both healthy and clinical populations. In this dissertation, we demonstrate fMRI data analysis ...
An efficient methodology for the partitioning of VLSI circuits using genetic algorithm
(2014-02-12)
In the recent years, with the explosive growth in the density of VLSI circuits, efficient algorithms and methodologies for circuit partitioning have been established as an important area of computer aided design for VLSI. ...
RFIC Design for Software-Defined Radio Receiver Frontend
(2013-11-11)
This thesis presents an RF receiver frontend with a 4-path passive mixer for software defined radio (SDR) applications. By utilizing frequency translation property of the passive mixer, the out of band interference experiences ...
Antenna Array Beamforming for Low Probability of Intercept Radars
(2013-11-08)
A radar system's focus on low probability of intercept (LPI) performance has become increasingly important as systems designed for electronic support measures (ESM) and electronic counter measures (ECM) continue to become ...
Impact of Correlated RF Noise on SiGe HBT Noise Parameters and LNA Design Implications
(2013-11-08)
This work presents analytical models of SiGe HBT and LNA noise parameters accounting for high frequency noise correlation. The models are verified using measurement data and circuit simulation. The impact of noise correlation ...
Relay Positioning for Energy Efficiency and Improved Performance of Cooperative Wireless Networks
(2014-03-31)
Cooperative communications in wireless networks have gained much interest due to their
ability to mitigate the effect of fading in wireless networks by achieving spatial diversity. One
of the techniques used in cooperative ...
