Reactive Power Compensatioin Device Design with Utilization of an Integrated Circuit Controller
(2011-04-06)
Reactive power compensation is necessary to increase the efficiency of current and future global electrical infrastructure. There are many methods for the design and implementation of reactive power compensators. This ...
Physics, Compact Modeling and TCAD of SiGe HBT for Wide Temperature Range Operation
(2011-11-29)
One of the remarkable characteristics of SiGe HBT is the ability to operate over a wide temperature range, from as low as sub 1K, to as high as over 400 K. The SiGe HBT investigated and measured in this work is a ...
Vernier Ring Time-to-Digital Converter Based Digital Phase Locked Loop
(2011-11-22)
Digital phase-locked loops (DPLLs) recently are widely explored for wireless communication applications. Time-to-digital converter(TDC)-based DPLLs feature a high degree of integration, easy calibration and high programmability, ...
Optimal Observation Selection in Magnetic Resonance Spectroscopic Imaging
(2011-03-29)
Magnetic resonance spectroscopic imaging (MRSI) is a completely non-invasive
method for obtaining quantitative information regarding biochemical parameters [1].
It shows great promise for use in basic physiological ...
Polynomial-Time Algorithms for Designing Dual-Voltage Energy Efficient Circuits
(2011-11-14)
In this work, we propose a technique to use dual supply voltages in digital designs in
order to get a reduction in energy consumption. Three new algorithms are proposed for nd-
ing and assigning low voltage in dual ...
Net Diagnosis Using Stuck-at and Transition Fault Models
(2011-11-02)
As deep sub-micron technologies are widely adopted in modern VLSI design and fabrication process, the shrinking size and increasing complexity of digital circuits make it more difficult to maintain a high yield. Diagnosis ...
Advanced Learning Algorithms of Neural Networks
(2011-08-26)
The concept of “learn to behave” gives very vivid description of functionalities of neural networks. Specifically, a group of observations, each of which consists of inputs and desired outputs, are directly applied to ...
Wall Following Algorithm for a Mobile Robot Using Extended Kalman Filter
(2011-05-10)
This thesis proposes a wall-following algorithm for mobile robots using the Extended Kalman Filter. The robot navigates in a known environment where the baseboard of the wall is used as a natural landmark and indentified ...
Built-in Self-Test and Calibration of Mixed-signal Devices
(2011-05-05)
Wide adoption of deep sub-micron and nanoscale technologies in the modern semiconductor industry is resulted in very large complex mixed-signal devices. It has then become more difficult to estimate and control device ...
Ultra Low Power CMOS Design
(2011-05-05)
The ubiquitous era of emerging portable devices demands long battery lifetime as a primary design goal. Subthreshold circuit design can reduce energy per cycle in an order of magnitude of nominal operating circuits by ...
