I think there just needs to be an "Organic Chemistry University" with degrees from all kinds of science programs and math! I have spent more time learning from this guy pursuing my online electronic engineering degree than I have from the classes/ebooks! I feel like half my tuition should be going to him!
Shouldn't you include some form of gain stabilization, such as an incandescent lamp across the inverting input, or a pair of back to back diodes in parallel with the feedback resistor?
Amazing, thank you so much! If I wanted a voltage output of 9V, how would I do that? Would I simply just add another Op Amp to the output? What would I need to add to that?
Or you could use an external power source and an op amp. But don't use multiple op amps to try and get it higher unless you have an external power source.
what about this design : Design an oscillator which is capable of producing sine, square and triangle waves with 5V peak in the frequency range of 100Hz to 10kHz. You can use the circuits you saw in the lesson while designing. Make your design using opamps. Give priority to the use of LM741 in your design.
Why does it oscillate? The only input you have there is Vcc and Vss but I though the power supply of the opamp is just powering the amp? How do you get the "external" circuit oscillate? Because when I tried this on falstad with the ideal opamp and it does nothing
The formula of Av for positive input is Av=1+(R3/R4) so you got gain 1+(68/33) a little bit more than 3. Thats the reason it worked.
you are right! i hope people see this because i was confused at the gain too, i had to check it out in wikipedia
Just started studying electrical engineering at uni and your videos are helping a lot.
Good luck with your studies. Got my BSEE in 1969 and now retired.
Bob Scher I hope I’ve chosen an interesting and fulfilling career path.

This dude literally knows every subject on earth 😳
Wizardry ,,, call the FBI , white house intelligence is in denger, we've an extraterrestrial 🤯🤯🤯🤯🤯
He is either god
Or 👽
agree.. HAHA
Hahaha literally the truth

Thanks for teaching us something.
nice content
sir, thank you so much.

The name "Wien" is supposed to be pronounced like "veen", although a lot of people do get it wrong......

Who like the video hit like👍
600mv is low . What is the unit that increase or decrease the voltage on this OP-amp
you could use an other opamp to buffer/amplify the output.
Or you could use an external power source and an op amp. But don't use multiple op amps to try and get it higher unless you have an external power source.
So nice if you make ametel detector that weel bi cool

Refer to book " R. A. Gayakwad, Op-Amps and Linear IC’s, "

You can be a university professor....he probably already is one lol
can we apply ac voltage as input to this oscillator?
If you like video hit like
What software is this you're using in presenting?
Is it inverting or not inverting ?
Av=1+(R3/R4) becasue is a non-inverting op Amplifier.
Can the 741 latch up as an SCR if the voltages are supplied in the wrong order?
Honestly, this circuit design process is still beyond me. I need more guidance about how to design these simple circuits. 😢
I've tried this circuit and I noticed that if I change the gain (R3 and/or R4) , I also change the frequency, why?
Would it work with a LM324N?
Wien is pronounced " Veen" rhymes with bean!
the op amp use in wine bridge is non-inverting so gain (1+(R3/R4)) you use (R3/R4) only !!!!!!!!!!!!!! this wrong
-------------please revision it
