In a book about computers I have this transistor diagram:
the first two transistors are p types and the second two are n types. I am wondering how it should have been drawn if we close the circuits, because as far as I know we must ahve closed curicuits to get electricity.
1. The first idea I have is that we must close the the ground with the power supply, is this correct? This part would look like this? Notice the top here, I have drawn the red line above the horisontal line, but maybe it should be just below the horistontal line?
Now I must draw the line in the subtrate in the transistors, here I have two options. I only draw one p transistor and one n transistor. Option 3a)
And maybe they would be short-curcuited if I draw it like I did, so maybe I should have added some resistors aswell? If the drawing are wrong, could you please explain how we would draw the full circuit?
