| Sep 6, 2023 at 21:12 | comment | added | Sophie Swett | I think that would be fine. | |
| Sep 6, 2023 at 21:11 | comment | added | volticus | Okay, thank you @Cassie Swett. This makes a lot more sense. But here is the thing: I still don't know why the inverter makes the AND-gate better and still can't understand the explanation in the linked post. Do you think it's okay to edit my post to remove the resistor mistake and keep question 2? | |
| Sep 6, 2023 at 21:09 | comment | added | Criticizing Israel not allowed | The problem with your AND gate is the output voltage is lower than the input voltage. If you connected the output to another gate, the second gate's output would be even lower. After a few gates the voltage would always be 0 so the gates wouldn't work. A good gate has to make sure the output voltage is at least as good as the input voltage (closer to Vcc when high, closer to 0V when low). | |

| Sep 6, 2023 at 21:06 | comment | added | Sophie Swett | You've mistakenly identified what part of this is the inverter. The inverter is not the two resistors at the top; the inverter is the resistor and MOSFET on the right. "Inverter" here means the same thing as "NOT gate." As far as I know, that's an ordinary NMOS NOT gate. | |
| Sep 6, 2023 at 21:05 | comment | added | volticus | @Hearth, The author of the post-question I linked asked why there was "an additional inverter part" in the logic gate. I thought I was referring to the two resistors. Am I incorrect? | |
| Sep 6, 2023 at 21:01 | comment | added | Hearth | What are you referring to as the "inverter component"? There is a part of that circuit that I would call an inverter, but it's not made of "two resistors". | |
