limiting amplifier's low corner frequency

The limiting amplfier is normally multi-stage cascaded. This required a DC negative feedback to provide offset cancellation.

My question is how we get the relationship between the lower corner frequency of the amplifier and the R, C parameters? Why it is related with the gain of the amplfier stages?

What is the impact if the lower corner frequency is too high?


I guess that the low corner frequency is the -3db frequency of the negative loop bandwidth. It looks like that if it is too high, too much low frequence component will be suppressed by the negative loop, is it right?

Thanks
