News - According to Pete: Curren…
about a year ago
Pete, there might be simpler ways to regulate current using discrete components, but current mirrors are actually very useful in ICs. You see, in an IC, a resistor is just a spiraling trace. You can imagine that a power resistor would take a large area on a 2D chip, as opposed to a smaller resistor and 2 microscopic transistors. You see them very often in opamps and many other stuff!
Anyway, your videos are awesome, keep it up!
