Hi
Have been thinking about compensation of opamps; look at this schemo: [removed]
This configuration has a noise gain of 6 dB; if I set C2=0 pF, I need C1=10 pF to make this stable (a well behaved load and source is assumed). But I can choose C2=100 pF (more or less blind guess) and C1=0 pF and it will be equally stable, right? Or anything in between...
So what are the tradeoffs here? What about slew-rate and high-freq (outside audio range) distortion?
Thanks for input!
