Schmitt Trigger LC Oscillator

Typically a Schmitt Trigger can very easily be made to oscillate. You just need to make a frequency determining RC or LC network, that will oscillate between the two threshold levels of the Schmitt Trigger and make a feedback for it to sense this oscillation. Now when the oscillations pass over the thresholds they will make the trigger response to this passing. If you can add a way to make the trigger pull some of the LC's energy at just that moment, you've got yourself an oscillator. Only problem is, this thing tends to work in a very specific voltage range. Anyway enjoy :)

To be precise, what you mean is an "inverting schmitt trigger".

Finally! Another circuit. Too bad this one isn't very interesting. You should make circuits more often now that @hurz has gone mad and decided to delete all his AMAZING circuits, and probably won't be making any more.

Jason, dont be to hard, he's young and is still learing.

This is pretty nice. I liked more the spinning wheel circuit made by hurz to make LC oscillators. That was a nice concept and circuit

Ah, yeah, I haven't been in the game lately, kinda preoccupied.

Whatever man, one more inverting stage is the difference. Get it over, jeez :/

I thought the difference was an inverter in series to the schmitt trigger

Well yeah, it's really not something to get worked over with.... Unless you mad :D

Buggzy's "typically schmitt trigger" which is not just a schmitt trigger, how typically?
