Design And Implementation Of A Signal Conditioning Operational Amplifier For A Reflective Object Sensor, Ankit Master

Masters Theses

Industrial systems often require the acquisition of real-world analog signals for several applications. Various physical phenomena such as displacement, pressure, temperature, light intensity, etc. are measured by sensors, which is a type of transducer, and then converted into a corresponding electrical signal. The electrical signal obtained from the sensor, usually a few tens mV in magnitude, is subsequently conditioned by means of amplification, filtering, range matching, isolation etc., so that the signal can be rendered for further processing and data extraction.

This thesis presents the design and implementation of a general purpose op amp used to condition a reflective object …

An Fpga Based Implementation Of The Exact Stochastic Simulation Algorithm, Phani Bharadwaj Vanguri

Masters Theses

Mathematical and statistical modeling of biological systems is a desired goal for many years. Many biochemical models are often evaluated using a deterministic approach, which uses differential equations to describe the chemical interactions. However, such an approach is inaccurate for small species populations as it neglects the discrete representation of population values, presents the possibility of negative populations, and does not represent the stochastic nature of biochemical systems. The Stochastic Simulation Algorithm (SSA) developed by Gillespie is able to properly account for these inherent noise fluctuations. Due to the stochastic nature of the Monte Carlo simulations, large numbers of simulations …

A Fully Integrated High-Temperature, High-Voltage, Bcd-On-Soi Voltage Regulator, Benjamin Matthew Mccue

Masters Theses

Developments in automotive (particularly hybrid electric vehicles), aerospace, and energy production industries over the recent years have led to expanding research interest in integrated circuit (IC) design toward high-temperature applications. A high-voltage, high-temperature SOI process allows for circuit design to expand into these extreme environment applications. Nearly all electronic devices require a reliable supply voltage capable of operating under various input voltages and load currents. These input voltages and load currents can be either DC or time-varying signals. In this work, a stable supply voltage for embedded circuit functions is generated on chip via a voltage regulator circuit producing a …
