Any time i try to learn about logic gates online i learn what they do, but I can never find anywhere than explains how they do it. For example, it’s easy enough to understand that a Not gate switches a 1 signal to 0 or a 0 signal to 1, but how this is actually done baffles me because how can you physically input a zero, or no current into something and have a one or a current come out the other side? is the current entering the gate through some other line, then only passes through if there is no input?. I would like to get a birds eye view of the physical structure that makes various logic gates work, if anyone can help, or if someone knows where i could find that information.
Thanks.
Thanks.
