Photodiodes Explained: How They Actually Work — Physics, Circuits, Speed, and Design Trade-offs
Most explanations of photodiodes stop at "light hits silicon, current comes out." This one doesn't. We build the device the way an engineer must think about it — from junction physics to equivalent circuit to real design decisions — and show exactly why every useful improvement comes with a trade-off. CHAPTERS 00:00 — Why the simple ...
