Gupta, Shivani (1995-02-24)
1/f noise of GaAs resistors on semi-insulating substrates, and 1/f noise due to temperature fluctuations in heat conduction

Choi, Mun-Seork, 1960- (2008-07-10)

This research work focuses on the mechanism of 1/f noise in GaAs resistors on semi-insulating substrates and 1/f noise due to temperature fluctuations in heat conduction in resistors, diodes, and bipolar transistors. T ...
A 10 bit algorithmic A/D converter for a biosensor

Rengachari, Thirumalai (2004-03-11)

This thesis presents a novel algorithmic A/D converter to be used in a biosensor. The converter is capable of a conversion rate of 1.5 bits/phase and hence the required conversion time is reduced. The proposed architec ...
A 2.4GHZ direct conversion mixer with offset cancellation

Schmidbauer, Hardy (2001-02-27)

Dynamic DC offset is one of the biggest problems preventing the implementation of single chip receivers. This thesis presents a 2.4GHz downconversion mixer designed to work with adaptive DC offset cancellation for a fu ...
20-stage pipelined ADC with radix-based calibration

Yun, Chong Kyu (2002-11-07)

A radix-based calibration technique was previously proposed with a two-stage algorithmic analog-to-digital converter (ADC). The objective of this work is to verify the capability of radix-based calibration for a true m ...
2D second-order asymmetric tensor field analysis and visualization

Lin, Zhongzang (2010-12-01)

The gradient of a velocity vector field is an asymmetric tensor field which can provide critical insight that is difficult to infer from traditional trajectory-based vector field visualization techniques. I describe the ...
Accuracy enhancement techniques in low-voltage high-speed pipelined ADC design

Li, Jipeng (2003-10-03)

Pipelined analog to digital converters (ADCs) are very important building blocks in many electronic systems such as high quality video systems, high performance digital communication systems and high speed data acquisi ...
Accurate and efficient simulation of synchronous digital switching noise in system on a chip

Habal, Husni (2004-07-09)

A new method is presented to compress switching information in large digital circuits. This is combined with an efficient approach of generating the noise signatures of cells in a digital library that results in an acc ...
Accurately tunable low-voltage continuous-time filters

Vemulapalli, Gowtham (2003-10-17)

A tuning technique which tunes the continuous time filter very accurately is proposed in this thesis. This technique overcomes the problem of master slave mismatch, thus tuning the filter accurately. The mismatch minimiz ...
ACTFEL device simulation with impact ionization using a two-sheet charge model

Bouchard, Anthony F. (1999-07-09)

The main achievement of this thesis is the development of a two-sheet charge simulation model with space charge creation by trap-to-band impact ionization to describe the electrical characteristics of alternating-curre ...
ACTFEL phosphor deposition by RF sputtering

Ang, Wie Ming (1992-12-18)
Active learning of constraints for semi-supervised clustering

Xiong, Sicheng (2013-04-25)

Semi-supervised clustering aims to improve clustering performance by considering user supervision in the form of pairwise constraints. In this paper, we study the active learning problem of selecting pairwise must-link a ...
Active learning with committees : an approach to efficient learning in text categorization using linear threshold algorithms

Liere, Ray (1999-12-07)

We developed and investigated machine learning methods that require minimal preprocessing of the input data, use few training examples, run fast, and still obtain high levels of accuracy. Most approaches to designing ...
Active matrix electroluminescent device power considerations

Beck, Douglas (1997-06-12)

An active-matrix electroluminescent (AMEL) design tool has been developed for the simulation of AMEL display devices. The AMEL design tool is a software package that simulates AMEL device operation using a lumped param ...
Active object systems

Choi, Sungwoon (1992-02-06)

An active object system is a transition-based object-oriented system suitable for the design of various concurrent systems. An AOS consists of a collection of interacting objects, where the behavior of each object is d ...
Active power filter for the cancellation of harmonic line current distortion

Merk, Marcel (2000-10-04)

With the increased attention on high efficiency and energy savings, power electronic energy conversion equipment is increasingly incorporated in all levels of the power system. The drawback of such equipment is the gen ...
Active robust control of cable-stayed bridges

Scheer, Dietmar (1993-02-26)

Long bridges tend to develop large deformations under the action of intense dynamical loads such as wind or earthquakes. Unless these deformations are controlled in some fashion, the structure might suffer damage or e ...
Activity recognition in desktop environments

Shen, Jianqiang (2009-03-19)

Knowledge workers are struggling in the information flood. There is a growing interest in intelligent desktop environments that help knowledge workers organize their daily life. Intelligent desktop environments allow the ...
Adaptation-based programming

Bauer, Tim (Timothy R.) (2013-01-31)

Partial programming is a field of study where users specify an outline or skeleton of a program, but leave various parts undefined. The undefined parts are then completed by an external mechanism to form a complete pro ...
An adaptive all-pass filter for decision feedback equalization

Wiedmann, Ralf (1997-03-06)

Increasing densities on magnetic data storage devices leads to problems of severe intersymbol interference (ISI), additive noise and non-linearities. Advanced detection strategies for magnetic recording channels fall i ...
