I took a class on semiconductor physics last semester taught by Professor Benyamin Davaji, ECE 7201, and our final was to write a paper on a solid state device or technology. I've been interested in photonics for a while so I chose GaAs-AlGaAs MQW heterostructures for photonic applications. Below is my short paper submitted on … Continue reading Multi-Quantum Well Lasers, GaAs-AlGaAs Heterostructures →

My interest in electrical engineering started in high school, the day our family computer died -- RIP. Up until this point I had designed some websites, written some code, built some computers. I thought my future was in web development and database management. Lame geek stuff. I opened up the computer, thinking I could fix … Continue reading Silicon to Software: how computers work →

I went back to school part-time to pursue analog integrated circuit (IC) design, and my first class for Fall 2021 was Analog IC Design with CMOS Technology. I've added a new page to my list of projects detailing my final project for the class, an instrumentation amplifier for EEG signals. That page goes through the … Continue reading My First IC – a mini memoir →

Today, we're going to build a single transistor amplifier, just to show you that the theoretical numbers and models you use in class do in fact serve a purpose. Okay so let's start with the premise. We want to create a single transistor amplifier that has a gain of 10, and works off a 9V … Continue reading BJT Amplifier – Concept to Components →
