Omnisound is an award-winning 3D audio system that incorporates headtracking to generate a highly immersive soundscape. Such a system with low latency, high accuracy, low cost, and high portability is highly sought after in the 3D audio field. After researching human auditory perception, it is found that latency exceeding 60 ms, or accuracy exceeding 8.3 degrees, would break the illusion of a 3D audio scene thats adjusts to head movement. Omnisound is able to meet or exceed these objectives. The design, construction, and demonstration of the system was conducted to meet the Senior Design Project requirements of the University of Texas at Austin. The project was awarded 2nd place in the Fall 2014 UT ECE Design Contest.
Low Power Op Amp design and simulation. This project is part of the UT EE338 course and describes the design and simulation of a low-power two-stage operational transconductance amplifier (OTA) using a 180nm CMOS technology and a 1.8V power supply. It is shown that with careful design, a low-frequency gain greater than 70dB can be achieved together with high phase margin (greater than 45°), fast settling time (less than 40 ns), and low power consumption (0.467 mW). The project was awarded 2nd place in a Texas Instruements sponsored Design Contest.
Buck, Boost, and SEPIC Converter design, build, and bench test. These three projects are part of the UT EE462L course. Each of these DC-DC converters as well as their gate drive circuit are built from discrete parts. The output DC and RMS voltages, power, efficiency, and output ripple are measured on the bench and compared against theoretical values.
H-Bridge Audio Amplifier design, build, and bench test. This is a three-part project, also a part of the UT EE462L course. Each of the three components of the H-Bridge system are built from discrete parts. The output signals are measured on the bench, analyzed, and compared against theoretical results.
Photothermovoltaic Solar Cell Development. This is an individual initiative project conducted between 2010 and 2011 that led to the development of a high-efficiency and cost co-optimized concentrator solar cell using a combination photovoltaic cells and thermoelectric generators. The project won several national and international awards and was named a finalist in the Intel Science Talent Search competition in 2011.
Etherlux: Novel Internet Controlled Smart Power Outlets (IOT). This is a currently ongoing project aimed to create a practical and marketable "Internet of Things" (IOT) product using various skills learned in the UT Electrical Engineering program. A fully functional internet controlled power outlet bank has been constructed and is being field tested. An ARM based single-board computer (Raspberry Pi) running an Apache web server is used to control a logic block connected to power electronics circuitry. [EtherLux website]
