Princeton VLSI Project by Richard J Lipton( Book )

5 editions published between 1982 and 1984 in English and held by 5 WorldCat member libraries worldwide

There are three major aspects to our project: ALI, Census, and Testing. ALI, our procedural language for VLSI design and layout, is now up and running. It has already been used by Dobkin and Drysdale to redesign a divider they previously designed on a graphics system at Xerox. In addition, LaPaugh's VLSI class has already used ALI for their VLSI projects. Dobkin is currently beginning to explore ways to create graphics interfaces to the ALI system. ALI2 the second version of our layout system is coming along well. The census language is a new way to express parallel algorithms that use a fairly loosely coupled method of control. Work is under way to understand the limits and powers of such languages. North is beginning to identify those problem areas that can be successfully mapped onto the census language. We are also thinking about implementations of census, but no implementations is yet started. Our work on testing divides into two areas. Arden is beginning to work on first silicon testing especially with respect to scanning electron microscopes (SEM). He plans to be on leave this spring and work with the SEM group in Munich. In the future we expect that we will be able to use a SEM that the Princeton Siemens group is about to get. LaPaugh and Lipton have begun to work in the area of production testing. They have already successfully been able to completely characterize the testability of prefix computations. Prefix computations arise naturally in a number of places: for instance, in carry-look-ahead adders. Such characterizations link the self-test of these computations with classic semi-group theory
Study of Electronic Transport and Breakdown in Thin Insulting Films by Walter C Johnson( Book )

4 editions published between 1974 and 1980 in English and held by 4 WorldCat member libraries worldwide

Recent progress is reported in an ongoing of studies of high-field charge-carrier injection, transport, trapping, and dielectric breakdown in thin insulating films. The investigations reported here include the generation of interface states in the Si-Si02 system by ionizing radiation and by high-field stress, the high-field generation of electron traps in Si02, a method for measuring interface-state densities at low temperatures, and studies of high-field effects in the A1203-Si system

Novel Digital Signal Processing and Detection Techniques( Book )

2 editions published between 1980 and 1981 in English and held by 2 WorldCat member libraries worldwide

In the area of narrowband signal processing, design rules are developed for optimum decimator and interpolator, a new efficient scheme using recursive filter for decimation/interpolation is proposed, and a novel approach to the computation of narrowband spectra is shown to yield substantial saving over conventional approaches. Results on the implementation of recursive filters with poles near the unit circle that produces significantly reduced roundoff error include a transformation technique, a scheme to modify the quantizer error spectrum, and a new computationally efficient low noise filter structure. In the area of nonclassical signal detection, several results were derived on nonparametric sequential procedures and on the quantization of signal for detection. In addition, a programmable charge transfer device filter is developed, several problems concerning ADPCM are investigated, results are obtained on FFT roundoff error including the prime factor algorithm, and an effective method of generating random sequences is studied

Efficient Algorithms and Structures for Robust Signal Processing( Book )

2 editions published between 1985 and 1986 in English and held by 2 WorldCat member libraries worldwide

The research efforts supported by AFOSR Grant AFOSR-84-0381 were directed towards development and analysis of robust estimation techniques for autoregressive (AR) and autoregressive-moving average (ARMA) models. Work on related system theoretic problems associated with parameter estimation problems for times series models and on square-root filtering for least squares state estimation applications was also carried out. Finally, an adaptive estimation technique for a class of piecewise (in time) stationary signals was developed. The motivation for our research arises from applications in signal processing including linear predictive singal modeling, signal detection, dynamic state estimation (Kalman filtering), and spectral analysis. The general goal of this research has been to put together ideas and techniques from statistics, signal processing, and system theory to bring new perspectives to such problems. Our research on various autoregressive modeling problems resulted from a desire to relax some of the assumptions made by previous researchers, in order to broaden the domain of application of the basic technique which has proved to be useful in a range of signal processing tasks. In particular, our efforts have been directed at the goal of obtaining allowing robust estimates in the presence of outliers in the observed signal and in modeling of signals whose spectral characteristics change abruptly from time to time
Research into Self-Timed VLSI Circuits( Book )

2 editions published in 1984 in English and held by 2 WorldCat member libraries worldwide

There are three major components to our project. The first is in the area of procedural design of VLSI circuits. The second is in the area of our census language, and the third is in the area of the testing of VLSI circuits. (Author)
Ultrafast Processes and Spectroscopy with Free Electron Lasers( Book )

3 editions published between 1987 and 1989 in English and held by 2 WorldCat member libraries worldwide

Femtosecond laser spectroscopy has been used to study carrier relaxation times in amorphous silicon. We find a relaxation time of 1 picosecond above the mobility edge and a relaxation time of 10 picoseconds in the bandtail states, after which temperature effects dominate the optical properties. Theoretical modeling of femtosecond spectroscopic measurements has also helped define what is measurable and what is not. Picosecond time-resolved reflectivity measurements have been performed during laser-induced phase transitions. The dielectric function of molten Si has been measured and superheating in the liquid phase has been observed to last at least 10 picoseconds. Work continues in both areas. We expect to expand the experimental program to other wavelengths thanks to the free electron laser. Keywords: Free electron laser; Time resolved spectroscopy; Amorphous semiconductors; Laser-induced phase transitions; Silicon

Electron Transport in Heterojunction Superlattices( Book )

2 editions published between 1989 and 1995 in English and held by 1 WorldCat member library worldwide

This is a final report describes briefly three accomplishments in the area of resonant tunneling through double-barrier devices made of GaAs/AL(x) Ga(1-x)As heterostructures. They are: (1) the first experimental demonstration of the importance of many-electron effect in transport through such devices, (2) a self consistent calculation to take into account the space charge effect and thus to extract spectroscopic information from the experimentally measured I-V characteristics, and (3) the first observation of an intrinsic electrical bistability
On systems with unknown or uncertain parameters( Book )

1 edition published in 1968 in English and held by 1 WorldCat member library worldwide

This paper considers the analysis and synthesis of several classes of systems containing uncertain or unknown parameters which may be modeled as random variables. Attention is restricted primarily to linear, time-invariant systems and to simple mean-squared error criteria. The analysis problem is straight-forward but computationally difficult. The synthesis problem is tractable only when the structure of the system containing the random parameters is well-specified. (Author)

Effect of Correlation on Signal Detection in Arctic Under-Ice Noise( Book )

2 editions published in 1988 in English and held by 1 WorldCat member library worldwide

Signal detection in a large segment of non-Gaussian and non-stationary Arctic under-ice noise, which contains both high power narrow-band and impulsive components, is examined. It is shown that the correlation functions of sub-segments of data change significantly, and if ignored, can degrade the performance of a detector. For a false alarm probability of 0.05 and a known constant signal, the matched filter was on average 17.6% better than a detector designed assuming independent noise samples. It is also shown that pre-processing the data with an adaptive notch filter, then using the matched filter will result in a further improvement of about 6%. Additionally, the effect two different signal shapes have on the performance of the matched filter is examined. Keywords: Acoustic data; Underice acoustic detectors. (EDC)

Noise Characteristics of Superlattice Energy Filters and Multi-Color Infrared Detection Using Quantum Well Microstructure( Book )

2 editions published in 1998 in English and held by 1 WorldCat member library worldwide

This report describes the result from a systematic study on a new device structure, the corrugated quantum well infrared photodetector (C-QWIP), which is designed to couple normal incident radiation into the quantum well structures. The C-QWIP structure is an array of QWIP wires with slant sidewalls, fabricated by etching V-grooves through the detector active region down to the bottom contact. It utilizes total internal reflection at the sidewalls of these QWIP wires to create favorable optical polarization for absorption. We have demonstrated that it has higher coupling efficiency in comparison with the standard 45 deg edge coupled device. Also, the coupling efficiency is independent of pixel size and wavelength. In addition, due to partial removal of the active material, the dark current of the detector is reduced significantly. The combination of photocurrent increase and dark current decrease results in a larger photocurrent to dark current ratio rI, and thus a higher D(*) and a smaller NEdeltaT in array applications

Voltage Tunable Two-Color Quantum Well Infrared Photodetector( )

1 edition published in 2003 in English and held by 0 WorldCat member libraries worldwide

Significant progress was made to further advance the quantum well infrared photodetector (QWIP) technology in two areas: 1) designating demonstrating, and understanding voltage tunable two-color QWIPs, and 2) understanding the light coupling mechanism in the so-called quantum grid infrared photodetectors. We have also been working on imprint technology to create pillars which can be used to enhance the performance of the photodetectors. The NIL molds with different period and different shape of the pillars have been created. Implementation of the small pillars to photo-detectors are in progress
A Coherent, Optically Controlled Phased Array System( )

1 edition published in 1997 in English and held by 0 WorldCat member libraries worldwide

An optically controlled microwave phased array antenna system is analyzed. Beamforming is accomplished with a large number of antenna elements that can receive any of several different true-time delays from a single fiber using multi-channel optical heterodyne techniques. System performance such as signal to noise ratio, signal to interchannel interference ratio, and dynamic range (DR) for various modulation-demodulation schemes (i.e. AM, FM, and PM) are quantitatively analyzed. An experimental system insensitive to laser linewidth arid IF frequency instabilities is demonstrated. Accurate true-time delay is demonstrated across the L band (0.8 to 1.5 GHz). The DR for one channel is 52 dB/MHz. For a narrow channel spacing of 1 angstrom at 1.55 micrometers, the interchannel interference is <-50dB. Also, monolithic photonic integration using vertical twin-waveguide (TG) structure based on single-step MBE grown InP/InGaAsP material is studied as a means of practical implementation of large scale photonic systems. Finally, high efficiency, high power semiconductor lasers employing a 1.5 micron InGaAsP/InP separate confinement multi-quantum well structure, are investigated for use in high DR, high density RF-optical links
