How do transistors figure into op-amps?
Why does the feedback make a difference if it goes to the negative vs. the positive op-amp input? Or does it not make a difference?
Why do we have
? Does it have anything to do with
in a FET?
What is meant by ``virtual ground''?
What is the general utility of Rule #2 of op-amps? I'm struggling to see how it's more useful that just a ground.
What is the difference between
and
transfer functions?
How does the voltage-current converter work?
For the differentiator op-amp, what is the difference between active and passive high-pass? Is this just when you input a voltage or no voltage?
Can you explain the intrinsic low pass filter for an op-amp?
How high does it take for amps to attenuate? Does it really matter?
