There are billions and billions of FETs in any modern desktop computer. But what do they do exactly? How do you get from unimaginable billions of transistors to computation?
You already know some bitwise logic. Transistors can do that.
Last chapter, we talked about NPN transistors with a load resistor on the collector. In this configuration, as the current is raised on the base, the voltage available at the node where the load resistor and the collector are connected drops. If that sounds like a logical NOT, as usual, you’ve got a good ear. Let’s work with that.
Imagine for a moment ...
