I see so many misconceptions about BJTs, people seem to either over-complicate the hell out of them, or over-simplify and then wonder why things don't work. I want to find a nice middle point, something overcomplicated that doesn't work. Today's post is to build a simple ground-up understanding of the BJT using fun analogies that … Continue reading WTF is a BJT?

Why are high impedances nodes slow?
I saw a great question posted the other day, why are high impedance nodes slow? Makes sense why that can be confusing, a transistor looks like a current source, multiply that current by a high impedance that must mean very high gain, why would that not be true at higher frequencies? Why does the resistance … Continue reading Why are high impedances nodes slow?
5 Stages of understanding transistors
The transistor will go down as one of the most consequential inventions in history, behind agriculture, paper, and the Super Soaker. But on the list of inventions that have completely transformed the very fabric of the human condition, it showed up pretty late in the game, and that's because it's a fairly complex thing. Conceptually … Continue reading 5 Stages of understanding transistors
