Fundamental studies of atomic diffusion by computer simulation of atomic processes on the giga event scale and multiple PC's in parallel

Creator:: Zhang, Qiongshan
Abstract:: The classic treatment of diffusion by Einstein and by Chandrasekhar assumed conservative boundary conditions; mobile species were neither created nor destroyed on the sample surface. It is normal to assume that vacancies and host interstitials are created and annihilated on incoherent interfaces or free surfaces; i.e., these are assumed to...

A photodetecting device that rejects ambient light

Creator:: Li, Ning
Abstract:: The integration of photodetectors with IC circuits provides a significant improvement over conventional designs. Featuring noise reduction, extended frequency responses, lower power consumption, and data operations, these integrated devices open challenging opportunities for many applications. One type of photodetector has the potential for important applications in the life science and...

A universal CMOS current-mode operational amplifier

Creator:: Botelho, Cindy
Abstract:: It has become customary in electrical engineering to think of signal processing in terms of voltage variables to the exclusion of current variables. This tendency has resulted in voltage signal processing circuits such as voltage-controlled voltage sources (VCVS) and voltage-mode operational amplifiers. However, the VCVS operational amplifier has several limitations...

A P-well GaAs MESFET technology

Creator:: Canfield, Philip C.
Abstract:: The semiconductor gallium arsenide (GaAs) has many potential advantages over the more widely used semiconductor silicon (Si). These include higher low field mobility, semi-insulating substrates, a direct band-gap, and greater radiation hardness. All these advantages offer distinct opportunities for implementation of new circuit functions or extension of the operating conditions...

A delta-sigma pulse width modulator with pulse dithering

Creator:: Lewison, Richard S.
Abstract:: Pulse Width Modulation (PWM) has been used extensively for motor control, DC-AC converters, DC-DC converters and in audio applications. The conventional method of generating a pulse width modulated signal involves generating an accurate sawtooth or triangle wave using analog circuits. In CMOS, being analog circuit intensive puts extra constraints on...

A microarchitecture study of the counterflow pipeline principle

Creator:: Janik, Kenneth J.
Abstract:: The counterflow pipeline concept was originated by Sproull et. al.[1] to demonstrate the concept of asynchronous circuits. The basic premise is that a simple architecture with only local communication and control and a simple regular structure will result in increased performance. This thesis attempts to analyze the performance of the...

Predictive control using feedback- : a case study of an inverted pendulum

Creator:: Barrett, Spencer Brown
Abstract:: Vision is a flexible, non-contact sensor that can be used for position feedback in closed-loop control of dynamic systems. Current vision systems for industrial automation provide low sample rates and large sample delays relative to other types of position sensors. Poor sample rates and sample delays are a result of...
