So, I kinda hit a threshold in a recent YouTube video when the announcer just casually threw out "the transistor acts like a switch..."
I'm kind of curious about the world proportion of transistors that operate in linear mode as opposed to being entirely off or entirely on.
So a typical computer would have millions of transistors in the processor and memory and GPU and whatnot that are acting as logic, and maybe a thousand or less that are in power supplies and in the monitor that are in linear mode.
So -- how many transistors are there in a modern switching power supply controller, and how many are on hard? Ditto in LCD screen controllers, and in hard drives, etc.?
I'm figuring that at any given moment the proportion of operating linear- mode transistors to operating "switch" mode transistors is probably on the order of 10^(-4) or 10^(-5) -- but that's just a guess.
