How does a NOT gate generate power?
I know that a NOT gate always inverts its input.
When the input is "ON" I can imagine the gate stopping the flow of current.
But how does the gate generates flow of current when the input is OFF?
Please could you explain how this happens as simply…

An inverter gate reduces the peak-to-peak of the signal!
Using a HCF4049 to invert a signal, I simply fed the input to one of its not-gates and got its output. Here is the result:
The highlighted red lines is the output of the not-gate. (Yep! my analogue oscilloscope can display colors, it knows how to…

amplifying out signal of germanium diode
Hello
Dear All.
Please see the attached pic. As you see i have used a germanium Diode and am going to drive to a logic gate (74hc14N). But the forward voltage of diode is 0.3v, whereas the 74hc14N can't active with it! So i have to amplify the…

Why are rise and fall times of a wave going through series inverters not dependent on first inverter?
I've been intrigued lately by the observation that if enough inverters are placed in series the rise and fall times of output waves become invariant to the delays of the input inverter. The chain gets a characteristic wave with its own rise and fall…
