Printed Circuit Boards (PCBs) are the backbone of electronics, the land we build on. To the average person, when you're thinking of circuits, you're thinking of PCBs. The first PCB I professionally designed (well, modified) There's a lot to say about circuit design, layout, signal integrity, safety, manufacturability etc. but I wanna get even more … Continue reading ABCs of PCBs

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
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?

Because I spend all day at work browsing DigiKey and reading articles about electronics, I get served up ads for textbooks, causing me to rapidly and aggressively re-evaluate my life. One of the books it advertised was titled "Wandering Spurs in MASH-Based Fractional-N Frequency Synthesizers" by Dawei Mai & Michael Peter Kennedy. This is the … Continue reading Find Your Niche
