Below are some of my write-ups for college projects, exams, and assignments. I would correct the plethora of erros I am sure they each have, but I enjoy keeping this page as an archive of my collegiate thoughts, conclusions, and problem-solving. Feel free to reach out in case something here catches your interest and you want to explore it more!
The Locality of Electrons. A one-day project for my quantum mechanics class. This project is accessible on the web!
Lecture slides for TLM measurements. I was asked by my former advisor to prepare a lecture on TLM (transfer length method) for his Solid State Devices class at TTU. This lecture went by fast, so I also explained GCIM (gate current injection method) for finding source/drain resistance on MESFETs/HEMTs...
Final report for my microwave antennas class. This final was split into two parts, with specified specs/antenna parameters for each student. Given that this was a summer course, it unfortunately went by really fast, but I certainly learned a lot in little time!
The Crank-Nicolson Method for Solving the Heat Equation. A final project for what is essentially a graduate-level review of maths we really should know by that point (linear algebra, probability/statistics, differential equations, etc.). We prepared all of this in MATLAB... Perhaps another tool I can make accessible on the site? (TODO: update this statement when I indeed implement a Python version here...)
Piezoelectric MEMS Speaker Design. My final design project for my advanced semiconductor processing class, I described a high-level design for an array of MEMS speakers heterogeneously integrated with other components, such as an antenna.
RF High Electron Mobility Transistor Research Project. I just want to come out and say: I don't like the title of this, but that is what the class wanted so that is what I got. My preferred title would be "Review of Processing Techniques for Performant and Cost-effective GaN HEMTs"... This was my first term paper for my advanced semiconductor processing class, where I reviewed mitigating strategies for channel-layer defects that arise from using substrates which are not of the same material.
Translation of RF GaN HEMT from Nextnano into Silvaco Atlas. My capstone project, it ended a bit underwhelming by my own admission, however I learned a lot. Originally the simulation aspect was supposed to be just part of the project, with the rest being characterizing physical samples, however the lab I was working with at the time was newly founded, so that had its own limitations. In the end, I decided to make the best of what I had... After this and many more attempts, I have found out that III-V HEMTs are not something Silvaco does very well. Diodes, though! Those are great!
Design of Simple PLL FM Radiophone. This was my RF lab's final project report, in which most of the components were working beautifully... Except for the demodulator! Initially we tried to make the demodulator from complete scratch (wound my own inductor coils and all for tuning), then we tried to use a VCO solution (turns out the output was not strong enough, IIRC), before we realized that we could have used a PLL demodulation chip the whole time... On the last week! So, it was a mad dash to the finish line, and alas... we burnt our last chip (first one lost a leg, and the surgery was not succesful). I still have the whole radio, actually, and I swear one day I will get another one of those PLL demod chips and fix it up!
Hans Off! The final project report for my microcontrollers project lab. The bulk of the software portion is accessible as a web-tool on this site!
Modulation Project. Aptly named, this is a simple project in my principles of communications systems (a.k.a. radios and digital comms) class in which we explored AM and FM modulation/demodulation via MATLAB.
Analysis of Designing a 4-Bit Shift Register Using VLSI Techniques. Essentially, I was tasked with designing the most performant possible 4-bit shift register in Cadence Virtuoso using a 1.6 μm process. TL;DR: How fast is it? 370 MHz...
Analysis of an Autonomous Rover. My first project lab, where we had to design a robot that autonomously moved and did a certain task. My portion in this project was the programming the logic and some of the movement, which was done in VHDL for an FPGA controller... As demo-day approached, I also may have had to make some structural modifications...
Homework 8 (Solid State Devices). A simple analysis of how changing gate oxide thickness and doping affects certain NMOS parameters. Perhaps like the CN project of S25, I should adapt and update this code to something usable on here?
Project One: Three Phase Circuit.
These were part of my network analysis class. I found out the hard way that network analysis had nothing to do with communication, but rather electrical networks (like power grids and such). Regardless, this was the first class I really started to write reports, and so this is kind of the set of projects that truly started my enjoyment of technical report writing.
