Behavioral modeling and digital calibration of pipeline analog to digital converters
(Texas A&M University, 2001)
This research focuses on digital calibration of pipeline analog to digital converters (ADCs) and also modeling of error sources and design parameters of pipeline ADCs. Modern applications such as communications systems ...
Spark-plug-mounted fiber optic sensor for measuring in-cylinder pressure in engines
(Texas A&M University, 2001)
A new design for an in-cylinder fiber Fabry-Perot interferometer (FFPI) pressure sensor suitable for automotive engines has been investigated experimentally. The FFPI sensor consists of a single mode fiber containing two ...
Wavelet-based progressive image and video coding using trellis-coded space-frequency quantization
(Texas A&M University, 2000)
Images and video are a very challenging topic in multimedia applications. Recently, with the explosion of the Internet, multiresolution source codes are necessary to better suit to the heterogeneity of the networks. This ...
A smart camera application: DSP-based people detection and tracking
(Texas A&M University, 2000)
As an application of smart cameras, this thesis presents an algorithm and its real-time implementation for detecting and tracking multiple people moving in a surveillance scene. The algorithm is devised to work for low ...
Low voltage amplifier architecture for high speed switched capacitor circuits
(Texas A&M University, 2001)
This work concentrates on circuit realization of high speed and low voltage switched capacitor circuits, with emphasis on the operational transconductance amplifier (OTA). An overview of switched capacitor circuits is ...
Passive polarization splitters in Ti:LiNbO₃ using crossed waveguides
(Texas A&M University, 2001)
Passive polarization splitters with crossed single-mode waveguides configuration for 1.55 [u]m application have been fabricated in x-cut y-propagating LiNbO3 using Ti-indiffusion technique. The operation principle is based ...
Threshold voltage extraction circuit
(Texas A&M University, 2000)
A novel optimally self-biasing MOSFET threshold-voltage (V[]) extractor circuit is presented. It implements the most popular industrial extraction algorithm of biasing a saturated MOSFET to the linear portion of its [] ...
Test point selection using wavelet transforms for mixed-signal circuit
(Texas A&M University, 2000)
With growing complexity of today's ICs, it is desirable to improve traditional testing methods to increase the throughput. If one can select a limited number of points to test the circuit from a given test pattern, the ...
Analog Rank-Order Filter using multiple-winners-take-all
(Texas A&M University, 2000)
I present an analog VLSI Rank Order Filter (ROF), capable of ranking a wide array of inputs. Implementation is achieved using two multiple-winners-take-all blocks that compute in parallel. Simulation and experimental results ...
Algorithms for revenue metering and their evaluation
(Texas A&M University, 2000)
Power components are measured for revenue metering and other purposes such as power control and power factor compensation. The definitions of the power components (active, reactive and apparent power, as well as, power ...
