GearHogs Web Design

During the Fall and Spring semesters of my Senior year I volunteered my time to help with a local high school FIRST robotics team.

My first project was to design and develop a web prescence for the team. After finishing that, I moved on to help in other areas, mostly assisting with programming efforts.

SensorCape

The SensorCape is a BeagleBone Black add-on cape that provides extensive sensing capability to the already very capable BeagleBone Black platform. The SensorCape was developed for the Texas Instruments Intern Design Competition. I wanted to design an add-on that was as versatile and capable as the BeagleBone itself.

Accomplishing this meant adding general functionality not included with the BeagleBone that would be useful in a wide variety of contexts. The simplest way to add functionality is to increase the possibilities for interacting with the BeagleBone. For me, this meant adding various sensors to enable the BeagleBone to know more about the world around it. To read more about the SensorCape and the incredible functionality it can add please visit the project page linked below.

Semiconductor Devices Reference

A useful reference sheet for MOSFET’s, BJT’s, and Diodes. Still in progress. Will cover common schematic symbols, first order model equations, frequency response models, and common uses and topologies for each device.

Download this, print it out and keep it with you through your electronics courses and during design projects, you will thank me afterwards.

PSPICE Behavioral Modeling Reference

As part of a research project I needed to learn quite a bit about behavioral modeling both in Verilog-A and PSPICE. I found myself constantly referring to the PSPICE ABM manual to remember the proper syntax.

Instead of wasting time flipping through pages, I made a one sheet reference page. I find it to be extremely useful and I hope you will as well.

Design of Two-Stage CMOS OTA

As a final project for my Analog Integrated Circuits course we were required to design and simulate a high-CMRR and low-noise two stage operational transconductance amplifier. The purpose of this project was to demonstrate an understanding of the various topics touched on during the course such as current supply design, amplifier design, stability analysis, and SPICE simulation of CMOS circuits.

My circuit was designed and submitted on time and satisfied 7 out of 9 of the design requirements. For a more in depth analysis, visit the project page.
