Operational Amplifiers No 11 Oscillator

A hysteresis or relaxation oscillator made with an op-amp.

Someone needs to make a 10 hour edit of this where the explanation just keeps oscillating. 😂 Great videos!

Stoners would get it after about 2 hrs.😄

Thank you, Bob! You are the Best Electronics Teacher I have ever seen! I really need to remember to click like, I'm sure it makes a difference. In 20 minutes, you put into my brain how to design a Relaxation Oscillator (Hysteresis Oscillator) using an Op Amp. It would take hours to figure out how to do this reading a book. I appreciate it! 🙂

I like your explanation, very clear!

[@vernonbosshard9317]

This reminds me a lot of the 555

Incroyable, merci

Thank you!

Hello Bob. I wished these videos had existed when I studied 36 years ago. Question: At the beginning both inputs set to ground. OpAmp output is set to 10V. Do you apply that initial voltage or does the OpAmp simply toggle to one or the other extreme by itself? Thanks Joerg

I appreciate the thorough explanation. How does it snap to 10 volts of output, where did the input come from ?

[@ronsone8373]

You feed an pulse or square to the input

Nice

[@Akeshma]

trying to simulate this oscillator using Circuit Wizard but failed to get expected results !

[@omiza3416]

How is possible for capacitor to goes -5v ?

It has a negative and positive power supply.
