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?

Misconceptions: small-signal analysis
One of the, if not the biggest hurdles to understanding transistor circuits -- and system modeling -- is small-signal analysis. As with all things, the reason it's difficult to understand is that professors are given very little time to provide context, so it's given or received like scripture on golden tablets in a language you've … Continue reading Misconceptions: small-signal analysis
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?
