Op Amp Open Loop vs Closed Loop Gain Response

The open loop gain of an op amp is very big, but the bandwidth is quite small. When you create a closed loop circuit, you give up some of that gain but get more bandwidth. This video goes into detail about why this is the case.

Hey nice Video, I would however like to point out, that for the Inverting amplifier, the gain should only approximate to 1/β for high gains. In fact, the total gain consists of the amplifier's gain and the input voltage divider, which is why for unity gain an inverting amplifier is more stable, as β = ½ compared to β = 1 in the case of a noninverting Amplifier 😄 This may not matter a lot for this introductory Video, however, I feel like this is an Important detail once it comes to stability analysis.

Amazingly clear and detailed! Thank you so much.

Hi, maybe you could do a second part of this topic which explains phase margin and open loop stability analysis. 👍

[@ElectronXLab]

Sure thing!

[@romero6157]

Thank you for the great explanation!

Thank you so much, you did a great job.... i'm in my 3rd year. you da best

[@MissionFitnessCTC]

Great video!

I gotta admit, that clickbait thumbnail where you swapped the plots really triggered me, haha

[@dmeemd7787]

Is -3.0 db still the best value to use when designing..? (where you'd measure your cut-off frequency at)

[@ElectronXLab]

Corner (cutoff) frequency is at -3dB

@@ElectronXLab Awesome, thank you!! I was trying to remember for one of my old engineering books and I wasn't sure if that was what they still use or not, thank you!!
