How smart can someone be who still uses AOL?

I very uncomfortable with the fact that you knowing all of that turns me on a little bit.

I just want to know how someone is turned on "a little bit" how does that work?

I'm not so turned on that I'd have sex with him but I'd let him kiss me.
God, saying is just so very wrong.

Haha, I cannot relate. You are funny.

It's an inverting amplifier circuit with a gain = - Zf/Zin. As you can see the gain of the amplifier circuit is totally independent of the intrinsic gain of the Amplifier device (Aol), because as Aol is a very large number on the order of 10^5 or larger, the quantity 1/[1+1/(Aol * Beta)] goes to 1. Therefore, the effective gain of the amplifier circuit is -Zf/Zin. This is a nice outcome as it permits us to achieve any amplification factor we choose, restricted only by the power supply level, of course.Imperium said:
I just proved it...I just don't have the scanner to upload my mathematical scribble to prove that other engineers are correct!

The idealized gain of -Zf/Zin (Z meaning complex impedances instead of pure resistance) starts to go to pot with an increase in frequency.
As frequency increases, the amplifiers open loop gain (Aol) starts to decrease because of the "single pole" roll-off...kinda like a low pass filter. The loop gain (AolB) must also decrease.
By inspection of the error term, one can see that the gain error increases when AolB decreases.
ZOMG McLOL. We are nerds.
And speaking of power supply levels, I had someone ask a question one time: "Can I use a string of opamps to amplifier my signal to +300V?"
