As a CS guy who got the absolute bare minimum introduction to electronics: why isn't the article about LC oscillators?
I get the impression that there was some requirement to use transistors that I was missing. The article briefly mentions some kind of inductor as a rare component.
- the__alchemist 1y agoHah! As an IC baby, I assumed it would be about what goes on inside crystal oscillators, TCXOs, MEMS oscillators, the difference between the one that you add 2 caps to with in and out vs the ones that don't need In and use a single bypass cap.
- tlb 1y agoInductors (the L of LC) are large and expensive except at very high frequencies. So audio circuits are normally designed with just resistors and capacitors. And you always need an active component like a transistor. A pure LC can oscillate for hundreds of cycles but not indefinitely.
