This post is for anyone taking linear algebra or wants to understand why they hated taking it. I'm taking a graduate level linear systems analysis course that's meant to serve as a primer to things like non-linear systems and advanced control theory, and I've been having flashbacks to what I think is one of the … Continue reading The Basis of Linear Algebra: Purposely Confusing Undergrads

Poles by Inspection, Zeros by Rejection
Hi everyone! Today I wanted to talk about poles and zeros, what they are mathematically, but more importantly provide intuition for what they actually represent in a circuit, and why it's so much easier to find and approximate poles while most textbooks either ignore zeros or "predict" them. An excellent text that helped me connect … Continue reading Poles by Inspection, Zeros by Rejection
Microelectronics Flash Cards
Before I started grad school, I made flash cards to refresh my microelectronics knowledge. I forgot them at my last job, but luckily someone found and beautifully transcribed them. It's like leaving behind a caterpillar and finding a butterfly. Huge thanks to Brian Casillas-Rodriguez at Bruker for taking the initiative! And as always, if you … Continue reading Microelectronics Flash Cards
WTF is parasitic capacitance?
I've always enjoyed the term "hand-wavey". It's such a stark contrast to what people imagine engineers do. You learn all this advanced calculus and linear algebra in college, and get a giant transfer function for your circuit and do the Laplace transform and draw a graph and there's all this talk of poles and phase … Continue reading WTF is parasitic capacitance?
